Apparently the CAPCHA or whatever was done to control bots has worked. I don't see near as many fake new users every morning and very few postings by them.
Well done!
Okuma Steve's people also found and implemented a much more advanced anti-spam add-on for the forum and it has definitely made a huge difference as before there was also a bunch of SPAM which ended up in a moderator queue for approval however this new system has been able to weed out nearly all of that as well so nearly nothing slips by or even ends up in that moderator queue.
