Hey there Chops,
I was thinking and thought it would be nice if you added a field in the account profile for a space to add the server that the guild is playing on. Then on the DKP's main page have a search field of the guilds on that server. The goal here is to have it to where the guilds can combine if they want to do instances together or just have guild wars. This would work well with the idea of a main chat room which I seen in another posting.
Again, just me thinking and it could very well be a stupid idea. LOL
That would be kind of neat with the new world PVP as you could do horde vs alliance guild in Silithus or EPL.
