I am a member on the HAAS website (or at least I signed up for the one year free- not sure if that counts).
I have browsed the site a few times but have never quite figured it out. I found it hard to get info about what goes on at meetings and auctions, where they are located, and who is invited.
When reading around on the site I always feel like 1) everyone knows each other because they use a lot of lingo I don't understand and have inside jokes, and 2) the main fish that everyone is interested in are cichlids (I'm not a cichlid person).
I don't frequent the site very often because of those things. Also just from reading threads on there it seems like the members are significantly more judgmental and critical of each other than members on this site.
