I added all the official Twitters, the WSRP staff Twitters, the Fansites, and the Errant Unit to the Realm of Role Play's twitter. It told me the Black Sky didn't exist, or I'd have added it to.
I have a personal twitter, but I mostly lurk on it. The Realm of Role Play
, an RP-focused blog I'm the Editor-in-Chief for, has a twitter though - @RealmofRP
As an aside, I added this site and the Scowling Cassian to the Realm's link list.
