@Lovius,
I think the name "founder" can easily be changed to "creator" or "administrator" or any other title. I don't see a bad side to the word "founder" but maybe "creator" is more accurate because even if you don't like it, YOU (Lovius) created! (for which we are grateful).
I think it is good that you have (as a creator/founder) some rights to chance the picture, description etc... but I agree with you that there should also be an option to create a group that everybody can adapt.
About the tool "ban a member from a group": it is not because you have that power, that you should necesarilly use it. I can imagine that you create a group only for your friends (calling the group "friends of Lovius") and if somebody no longer is your friend, you can then ban him, without the need to ban him completely from BW.
Does that make sense?
Anyway, I just created a croup called "Music Reviews". If some of you have a nice song or record to review, I would appreciate it if you could join that group...so that I can experiment a bit more with Lovius' remarks/suggestions
