Thanks to spammers, their puppets and their bots, we have revoked guest posting privileges from the forums. Sorry folks but now you'll have to be a registered member to post in any of our message areas.
Registration is free but you should be warned that signups are closely monitored. If you haven't activated your account when a certain period of time passes, it will be deleted without mercy. More than enough time is given for activation. It is all too easy to tell when an activation won't be done.
I don't guess it would hurt to say that it doesn't do any good for spammers to try to register to get backlinks in their member listing because the search engines aren't allowed to view those listings anyway.
Additionally, no one has access to several profile fields and trying to force data into one of those fields will do nothing other than to get you blocked automatically. All registration and login attempts are logged and monitored. ISPs are contacted on a daily basis concerning spamming attempts.
