I change the rank of general thread to non member, so anyone can view and post without creating an account. The problem is that now you can't even see the thread at all =/ Any suggestions?

I'm not sure I understand what you mean here. Did you change the rank of the general Thread Tag, or did you change the thread tag of a particular thread?

That said, no one can ever post without creating an account.

I just wanted to avoid the non members on creating an account. Thankyou.
