I've used the cforms II plugin to create the form that you see in this post.

The website is built using buddypress so that we can have membership features and forums. But any suggestions on how I can make a restriction so that only site members can submit the form? I'd like to keep it in a regular post and not in the forums, though I suspect I may have to move it to the forums for this to happen.

Please advise. Thanks in advance!
