Can I search this site for videos if I know the title or producer or description?

Yes, you can search the Members site using the search box in the right sidebar. Just type in any word that you know is part of the video, whether it's the title, the producer's name, or the description.

For best results in a Google search, just enter "Gimmee" before the terms you're searching for. So, if I wanted to search for the video 'Easter Island' by Zhan E Lee, I could go to Google and type

gimmee easter island

or I could type

gimmee zhan e lee

and either way the video I'm looking for will be in the top results.
