Have you tried running Play by Post here on CotI? I ran my SBRD campaign here on CotI as a PbP and really enjoyed it, especially having some dedicated Traveller grogs as players. Yeah, it got slow and dragged sometimes, but that was probably my fault as often as the players' - I was dealing w a lot of pain and related medications, diving back into Traveller as escape and distraction so I was usually online more often than the players, but sometimes it knocked me out so completely that I couldn't post in a timely manner. Still, it was a lot of fun and lasted about 16 months, IIRC. Links in my sig if you want to check out the threads or the Traveller-subwiki that I used for library data, subsector maps, etc. (Game was set in sorta-ATU in my idea of Reavers' Deep and Daibei midway through the Long Night.)
