Two Clan ideas:

I like the idea behind making it easier to try to recruit and find clans with out having to get spam invited by a bunch of young kids on a global chat. The only thing I would like to see added into this is on the players profile add a little more details. For instance a clan leader can see how many times a clan less member has left a clan during a war, also has the member every been booted from a clan, if so maybe a reason why. Maybe show how many clans that member has been in the last month or weeks. Also to help stop the war spy's maybe show the names of the last one or two clans that member has been in.
