I would ask those members to reapply with the new email address. Or you csn simply add the new email address. If necessary, you can merge their old topics once they start posting.

There is no limit to the number of things that technically challenged members/account holders might want or ask for help with. Some things they are best learning to go on their own. You csn walk them through it. You can create your own group’s personal help wiki pages or sticky posts.

I remember being shocked when the “change member email” feature was implemented, at how much power it gave me as an owner, and at the realization that I had to treat it respectfully, and the subtle simultaneous realization that other group owners might not.

It just feels wrong.

If a member is an owner of another group, this feature provides the ability for a nefarious group owner to take over that other group, by changing the email address of the member to a new email address controlled by the baddie.

I have changed the feature so that you cannot change the email address of a member who is a moderator or owner of a group.

Should I make other changes? Should the change only affect that one subscription? That is, if someone is subscribed to 2 groups, and the moderator of one of those groups changes that person's email address, should I then create a new Groups.io account, splitting off that one subscription?

Thanks,
Mark

I would disable the ability to change the address if the member is even a member of any other groups. That's because the other groups may have sensitive information in their content to which the baddie should not gain access.

Or, make it apply to this group only. But that will be fraught with details when the new address is already an account or an alias of an account. It may be worth delving into those details if it heads us in the direction of making it possible for the member to split their account, and/or move subscriptions between accounts (having somehow authenticated ownership of both).

Actually since your fix, they can’t do it to me. So I csn see this leading to people artificially making themselves group owners in order to benefit from the enhanced security protection .

I’ve always felt queasy about the ability of a group owner to change the account address of anyone at all. That piece of data belongs at a higher level than the individual group. 

As a member of several premium groups, I’m wondering now whether group owners might do this to me. Prior to this I’d only thought about it as a group owner. I’d push for eliminating this ability entirely.

Mark -- Thanks. This has bothered me for awhile now.

Correct me if I'm mistaken, but I think the most common scenario behind the existing feature is when someone simply gets a new email address, leaving the old one inactive. In such a case, the current behavior -- having the change occur account-wide -- strikes me desirable. 

If the account was to be split into two, it raises the question of how to subsequently merge them...especially if the previous address is no longer accessible. Generally, it seems to me that if an account holder is struggling to change his own address, he isn't going to be any more adept at merging them.

A third option (which probably won't be popular but I'd like to throw out for consideration) is the elimination of this feature altogether. As group Owners, we cannot edit a subscriber's profile, but we can change their login credentials? That combo has never quite added up to me.

Bruce


moderated Add DisplayName in the "joined" notification #suggestion

 

Hi Mark,

It can be useful in certain situations if DisplayName is added in the mod joined notification text, i.e.

This is to notify you that DisplayName ...@... has joined your group...
or alternatively,
This is to notify you that ...@... (DisplayName) or [DisplayName] has joined your group...
Even without the bracketing it would help catch if someone (user or mod) forgot to add a DisplayName on the profile (when this is a group policy), and especially when working with a multi-mod group in such group.

Thanks and Cheers,
Christos

Is that an owner or mod of a main group only or does it include mods of subgroups which may be just members in a main group?

Along with the power to change someone's email address come the responsibility to use it wisely. I always get confirmation from the member in question that they understand that a change to their account address impacts all groups they are subscribed to.  Unless I get that confirmation, I don't make the change.  It can be lot less time and effort being able to make the change on behalf of someone than it is to recover the situation after their failed attempts.  It accounts are split based upon subscription I think that will generate confusion for some older members who will login with the wrong account for the group they want to interact with and wonder why they cannot access it.  Those are frequent questions on GMF.

Andy

If you continue to allow email addresses to be changed, then I'd certainly prefer that it only effect one group.

Mark, I think I've said this in the past so I may be repeating myself.

I do not think I should have the ability to change anyone else's email address globally, if at all. I consider it just too much of a security risk. Members can do it themselves quite easily (I've provided folks with instructions a number of times). If they can't do it because they no longer have access to an email account, that's their issue to fix, not mine.

$.02,
Pete

Hi Mark,

It can be useful, if you add the user name as well in the mod notification text:

This is to notify you that UserName ...@... has joined your group...
or alternatively
This is to notify you that ...@... (UserName) has joined your group...
Even without the parentheses it would help catch if someone forgot to add a username on their profile, especially when working with a multi-mod group.
