Another PL suggestion!: Add a guild list....

I think a list of all the available guilds in game is a amazing suggestion! This way you know what guilds there are to choose from, you can send a "guild join" message to them so Guild owners can accept or reject players who want to join them.
Following on from this, you could find a player whose guild you like the look of, and press to button to send a guild join request.

Please tell me what you think of these and if you would use it!

I think this would be a good idea, also there should be some sort of mailing system. Not like messaging but you could actually send mail, that's another idea of mine and I won't go into it too much. ill be making a thread about this soon. :)

Would add A LOT of lag to the server. This is sort of the purpose of forums. Just check out the Guild sub-forum and everything you need is there!
