New Firewall.cx firewall ...so to speak

The module added will request confirmation only once. After that, it will recognise your IP Address and allow you to post from it without requiring further confirmation.

Ah, I hadn't thought of that. Obviously, I have a static IP address. If it was dynamic, I'd have seen the dialogue again.

I'm glad that it's working to stop the spam. Maybe I'll suggest a similar functionality to admins of other fora that I visit because several are subject to spam.
