I'm a moderator on e30tech, although I'm not active on the forum now, for a variety of reasons.
Sadly, the only person who can activate accounts is the forum owner, Chris, and he only seems to tend to business once every two or three months.
I'm not sure what his reasoning is, or why he won't let others approve new members.
The forum traffic has dropped dramatically. There is still tons of good info and strong contributors, but the forum needs nothing more than a bunch of new blood, like yourself.
I'm sorry you haven't had any luck with e30tech.
M42club is incredibly helpful for e30s with the twin-cam four! :-)
Cheers,
