I work on the second floor of Meyer, usually people there are pretty good about helping. We have our own wiki, on the Stanford servers just type in 'mms/wiki' to get there.
We have tutorials for Photoshop, and basic how-tos for programs like Audacity. Or how to import copyrighted clips through Fairmount. We can also help you use things like your AFS space (that free web space every Stanford student has).
Right. Well hope that helps.
