I put Show Info 2.0 up in the uploads area. It is also available off of the AMUG CD Roms. It enables you to add descriptions to your files before you upload. It features drag and drop capabilities so you can do batches of files at a time.
One other terrific feature is that it will auto uncompress files using the stuffit engine.
A must have utility for this system anyway. I have also attached it to this post.
