If you are like me, you like Babylon5 and like being able to say hi to the staff of the show. Phoenix Comicon 2013 was your best bet, but Galveston TX will give you another opportunity. The actors for Ivanova, Delenn, Lennier, Lyta, Talia, Na'Toth, Ta'Lon, Lochley, Zoe (...she was in one episode!), Londo, Vir, and Garibaldi are currently set to appear, with at least four more guest announcements waiting in the wings.
Space City Con's official website has info, and since Claudia Christian likes thefacebook, she's facebook promoting it as well. Zathras says check it out.
