Since it would be impractical for a moderator to be able to load and test each submitted file, I would suggest that submitted files be virus scanned then separated and posted into two categories.
1. SatelliteGuy Member Tested
2. Untested
If possible, a rating system should be implemented for members to rate the file and maybe an area to leave a short comment.
A subforum could be available to facilitate discussion threads on the files.
This sounds like a good plan to me. Maybe a warning in this section too stressing the importance of only posting factory firmware, etc.
