I haven't known Brian, quite as long as Val, but I've known him for a freakin' long time, and I'm going to miss the hell out of him. You guys already know about him, and his family already has my condolences, but I wanted to post still.
Valgav, and I, and probably Xanilus(I haven't asked him) are going to do some sort of contest/celebration of Brian here in the writers forum.
More than likely some part of it will be the Trigun fanfiction contest that Brian and I never got to run together, and another aspect of it will be Kenshin/Shishio fanfiction, for obvious reasons.
I don't know crap about the specifics of it yet, but I've been obsessed with the idea of honoring his memory, so I'm telling everyone in advance, in the hopes that we get some stuff that Brian would appreciate.
