To be fair, I've found this to be the most helpful all-round site.
The best techies hang out here, and they seem to be willing to go out of their way to help you.
Also, more Classic users are to be found here than Amigaworld.net, as that is mainly an A1 / OS4 site.
EAB is quite well attended as well, and not so shall we say strictly moderated!
