Required information for attaching specific filetypes

[coRtALoS]

I run a gaming website. To help people get an idea of what they're downloading before actually doing so, I'm looking for something that requires the user to enter specific information about the map in that can be viewed in the postbit.

The information fields would need to be either textboxes or radio checkboxes that must be filled out (character minimum for textboxes?) before they can be uploaded, and only applied to specific filetypes specified in the ACP.

While this could easily be done in the user's post, not everyone remembers, and it would save on unnecissary replies if the information we wanted was included in their original post.
