I first met Chris Croughton at my first full Worldcon, Magicon, in Orlando in '91. I enjoyed hanging with him at cons where we were both in attendance. He was friendly, fun, and someone I always looked forward to seeing. I also chatted quite a bit with him online (the two of us both being tech-geeks and around the same age). I remember how he beamed when he accepted his Filk Hall of Fame award when he was at FKO with the N'Early Music Consort. He later told me about how hard it was not to "burst out" to anyone about it.
I enjoyed his cheerfulness, his knowledge, and most of all, his sense of humor.
