It would be very useful if you could provide some sort of CSV output on your guild search page
I'm making an addon which will import the data from a website in-game. The basic requirements would just be name,class,spec,role,score. However, if you could include boss statistics too (how many times each boss has been downed by each player on each difficulty) then that would provide us with some very valuable in-game information.
Thanks for WoW-Heroes Give me a shout if you need any addon-related help.
