Clan officers now can edit Clan Profiles
There you can put info about your clan activity (Rifts, Bounties, PvP), difficulty level, recruitment info, etc.
Please contact me if you want to be included into the profile admin list of your clan (battletag: kernel#2961, email: admin(at)wowprogress.com).
By the moment we have over 300 clans in our database, and the next step is going to be Clan Search, so players would be able to find clan activity they like.
