Guests do not have the right to post due to spam, they can only view.
On the other board people were automatically added as members once they signed up. On this board we have to approve people before they are signed up 100%. It's a judgment call whether someone is legit or a spammer. Some are obvious and some are a bit harder to tell. Neither Tapper nor myself have the time to check every e-mail/domain that trys to sign up so sometimes it's better to sign an accidental spammer than kill a real e-mail.
If you see a name that says Guest, it's because I have deleted the account after they were registered, but haven't deleted the post. Once I find the post I nuke it.
For those that pm me the info regarding who they think I spammers, I appreciate it. Please keep it up.
