This certainly is a useful thread. I haven't met anyone yet, but I hope to meet Marina Sirtis at Fedcon this year. She seems like a nice person and I've heard good things about her convention persona.
By the way, I'm a bit disappointed in this year's Fedcon line-up. Being the 20th edition and all, I honestly expected more and bigger Star Trek
stars. For now, the only Trek actors announced are Marina Sirtis, Garret Wang, Wil Wheaton, Nicole de Boer, Carel Struycken (Mr. Homn), Arlene Martel (T'Pring) and Kate Vernon (Valerie Archer, VOY). I'd say that's a tad thin.
Well, considering it's my first convention, it'll probably be fun anyway, but there's only one person in there that I'm actually excited about meeting and that's Marina.
