requiring a form before allowing creation of a certain content type node

Hello!

I have another question regarding the control of certain content types. Let's say I have a content type that allows uploading of files. But I want to be sure that before any files are uploaded by the user, they check a box saying they agree to the terms & conditions for uploading the content. So my thought was a very basic form, of course, with a checkbox, but how do I enforce the form being completed before allowing the upload? The user would see a page that outlined the conditions, had a checkbox next to an "I agree" with a submit button...when they click on the submission button, the next page says either "Thank you for your agreement, please upload your file," or "You did not agree to our terms and conditions, please go back and check the agreement box". In the first case, the upload option is present, in the second, the upload option is not.

I am new to drupal, but experienced with unix, websites in general, perl, mysql, programming, etc. I have a working 6.11 installation with everything at its latest version, no problem. Just trying to figure out how to use this. It's entirely possible this is covered in the documentation, but I didn't have any initial success in searching through it so far.

NB: I have come across the workflow module, but it appears to have zero documentation and zero examples... if that would do what I'm looking for, any pointers to examples or tutorials on that would be wonderful. Or, if there's some way drupal itself can do this, or a better documented module, that'd be great...

Thanks,
