phpBB Customizations

I have an active and busy phpBB installation and we now need to make the following customizations: 1 Scan IPs - Firstly, the system would have to record the IP address of each user. Then there would be an admin function to allow the moderator to ban particular IP addresses from posting.

The moderator must approve of posts for all unapproved users before they appear on the site, but approved users can post at will. 3 CAPTCHA - All new users must pass an anti-SPAM CAPTCHA system in order to register. We will thus implement this: [login to view URL] These modules (1 and 2) are to be written to be reusable. NOTE I HAVE NOW REMOVED ITEM 1.
