I have a client that would like commenters to click on a check box to say that they agree to the terms and conditions of the site. Basically, if the user doesn't check the box, then their comment won't be accepted. The site also uses recaptcha. Does anyone know of a plug-in that can do something similar to this? I've looked through some of the anti-spam plug-ins and I couldn't find one that fits the bill.
Thanks!

What about using a checkbox custom field?
I'm not that familiar with custom fields...can I then setup an if condition that if its not checked, reject the comment? I suppose I could write some javascript..
I would recommend against using javascript for this unless you are happy with the illusion that the terms and conditions have any real value or meaning. Anyone with javascript disabled or spam bots will not be affected by this at all.
It should be a relatively simple plugin for someone to make. Perhaps someone here would like to volunteer their time, or you could outsource it.
While I haven't tried it, I think adding a "user"-type checkbox custom field that is required should do it. The field should just appear on the user registration screen. Then, being a required field, it'll have to be checked for the registration to complete. I think. I haven't actually tried this.
Custom fields are a part of the Professional Pack in Movable Type Pro.
Using Javascript to help ensure the field is checked is good, but as Wireghoul says, won't actually ensure that it's checked. However, marking the field as required when you create it should do it.
