I had a form set up in cforms in which I forced the users to log in before filling in the form by pre-populating the name and email fields with {CurUserName} and {CurUserEmail} and making those fields BOTH read only and required. If they hadn't logged in the fields were blank, but they couldn't just type into them because they were read only. It worked great.
I'm trying to find a similar, or any, way to force users to log in before filling in the form. I can do the pre-populate thing with GF but it looks like there is no way to make a field read-only.
Any other suggestions?
Thanks!
