I'm very glad with this plugin. I needed a link that could pop out a form so that my members could submit the reason without going to another page.
PopFeed does that really well:
1. Very light and fast when opening the form
2. FULLY customizable - you can customize the form so that it appears like you want
3. The developer is extremely receptive and helped me integrating POPFEED with DOCman.
4. Does it need more? IT'S THE BEST REPORT PLUGIN BY FAR!
