Hello, now that's it's been a few weeks and things seem to be working, I'll let you know about a big change I made to the registration process. In order to FINALLY make progress against all the spam, I've instituted a change where all new accounts must have their first post approved by me.
So now I'm the only one who sees spam messages. If you're a new user, please know that I'll get to approving your post(s) as soon as I can. I check the boards several times a day.
Hopefully, this has lead to a better user experience!
