Here's another registration suggestion:
I have been monitoring new registrations on my .Classic board (soon to be upgraded to Threads) using an IP locator site, (
http://www.domaintools.com/ ) and I am getting around 2 per day from spammers or hackers. The board is very localized to California hiking, and a new user from India or Russia or China is pretty obviously bogus.
It would sure be nice if there was a way to check the IP origin of a login, and throw the questionable ones into a Registration Approval Queue, while allowing new registrations from anyone else.
