Lets say they're called 'captchoro'
And if we use that as the registration method to catch spam, it uses images we design and upload ourselves, along with the answers.
These would all be custom made for each forum by their respective admins.
Now the added benefit to providing a custom method of spam prevention would also be to generate some added $$$.
By this I mean to create custom 'captchoro' images like this.
Then you can sell these to your advertisers and also provide an added layer of spam protection.
What do you guys think?
