Hello,
I'm quite new with Xwiki, evenif I used tu use wikis since a long time, especially swiki (dyed), editme wiki, or mediawiki. I would like to make a little remark about users and groups administration (and maybe the whole administration) ; the ergonomy is not very good up to now, compared to other tools (for instance edit me wiki)... I've seen that you started to develop modules with GWT, and it isa good thing. Maybe a more friendly manner to administrate users and groups could be good.
Best regards
Xavier
