We have a video in the Pending queue that has a producer logo at the end.

It is a wonderful upbeat video that is well shot and very well edited.
Our stated policy is no commercial content.
However, we now put the Producer .org username on the main video page and we have allowed company logos on slides that show in the video (with limits).
So do we need to re-examine the “no producer logo” at the end of a video also? Especially for those who volunteer their efforts.
