how about having a wiki.undernet.org ?
where users can edit it. history their channels, their irc lives ... etc
its also useful as it could provide lots of information about anything related to irc.
you have some few lines of history on http://cservice.undernet.org/live
about your username of channel(s).
now what would stop users writeing lies about their channels in an official website like this one you are talking about ?
My opinion is that only officials should give this kind of infos and this if its strictly needed.
