So... I recently joined this server on the Sylvanas realm and from the looks of this forum there are at least a number of people interested in roleplay.
As such I propose the use of a custom channel "RP-OOC", which would help in finding other people interested in roleplay, plan some events and all that sort of thing.
This is something we used on another server I roleplayed on some 2-3 years ago and it worked pretty well.
