frags for next reef meet

[Matt]

Someone help me with the protocol here. I've been to another reef meet (thanks Michika), but never participated in a frag swap. Do folks bring them on spec? Do you need to "dibs" them before they arrive? How do values get squared on frag exchanges? Should I bring a pocketful of fives?

As I mentioned, I can bring some anthelia, some green zoos and possibly a colt frag. Should I bother? Nobody has indicated any interest, but I don't know if that means anything...
