Reading all the support for the thread I began and this time WITH coffee -
So you are asking that I bump the storage for the free version to 15 gigs in the hopes of luring a group to come over that, 1) has never paid for service before, and 2) does not see the advantages of Groups.io over Google Groups. Not trying to be rude or anything, just trying to understand.
Also, where does the 15 gigs of storage number come from? I'm unaware of any storage limits with Google Groups.
With your car analogy, I would go more with Groups.io being a BMW or Mercedes, not an Edsel (ie an upscale offering for people who appreciate the extra features/service/focus of Groups.io over Google).
