Alexis,

I did a quick test and if you generate a text only message using an email client  (eg Gmail) with a fixed width font, it renders properly when viewed on the groups.io web interface. Since there seems to be no way to chose a font online when composing, I don't see how you could directly generate a fixed width font post online.

Here's a sample I just pasted from a text message i sent to myself earlier for testing.

Fixed width font    < 4 Spaces     < 5 spaces

sdjhsdjklkjsadkj    < sdsadkjsdkl  < skldjasklj

 

The above rows should be aligned.
