Registering for the forums is now easier (for humans) because yesterday I switched the spam-preventing service to a different one.
If you're a robot, you'll probably still struggle with it.
If you know someone who tried to register but couldn't because they couldn't pass the Captcha ("letters and numbers") test during registration, please let them know it's much easier now.
As always, you can register using the "Create Account" button at the top right of any forum page.
By the way, the whole reason to have the Captcha test is to keep robots from registering in the forums and then spamming us like crazy. We definitely don't want that.
