Besaid was the original unofficial RP server, and later it became Balmung after the merge. The server was selected by the RPC (Role-Play Coalition
) based on popular vote. Most of the 1.0 RPers (so far) intend to stay with Balmung, and the majority of newcomer RPers are leaning that way as well. That said, there is also a group of RPers who wish to start on a fresh "non-legacy" RP server. The RPC will possibly hold a vote for this and support their endeavors, though will likely remain largely stationed on Balmung.
This is of course pending information from SE. We do not know what their plans for an official RP server are yet, but they stated they're looking into and we expect to probably hear more within the next couple weeks or so.
Speaking of... did anyone ever listen to the Remotely Plausible podcast? It wasn't the best podcast (ran a bit long with hardly a format or anything) but I always found it entertaining.
Further Info: It was a GamerEscape podcast that talked about their role playing adventures.
Yeah, that podcast originally formed under the RPC and then branched out to Eorzeapedia/Gamer Escape. It's no longer around, though I know there are some RPers out there who still do podcasts. The focus is much more on random chatter and game stuff moreso than RP I think though. I'll have to find out more about that.
