I fail to see what's so wrong on Amibay. I did only start using it few months ago and it works for me. That's because I only use it for finding a part in need, or sell some that I don't need.
I must admit I see lots of moderator's arse-lickers constantly quoting from the forum rules because someone might get away with the part THEY want in a way that isn't 100% according to those rules.
But what the heck, all Amiga forums these days are full of a-holes these days. It's either living with it or finding another hobby.
