I used the user registration solution to create pages for models
I then used security assist to create the user table for photographers and set up restrictions so that only loggied in users of the photographer group can see the search and results tables from the user registration fopr models.
This all seems to be working (Shhhhhhh!!)
I now notice that the registration page created by security assist does not contain a captcha element.
I search on the web tells me I should use the validation toolkit but that is it appears no longer available.
How can I add this security?
