I have checked the box that allows anyone to register. But there are an indordinate number of spam registrations. While there appear to be a number of plugins that add a captcha, these same plugins have huge files. I worry that they will slow things down considerably.
I have stared at
http://codex.wordpress.org/Function_Reference/wp_register
hoping to see something about adding a simple question (that only a real person could answer) to the registration form - along the lines of wp-gatekeeper plugin for the comment form. Alas, there is nothing there.
I find it quite remarkable that this is not something that is automatically added to the core wordpress, with instructions on how to change the question and answer. (search results for [registration captcha])
Can someone lead me to where I should look to find out how to add this required question to the registration form? I'm guessing that it has to be added somewhere on /wordpress/wp-login.php and/or /wordpress/wp-register.php. Are there other files that would have to be changed as well?
Thank you for any help you can offer.
