Save/Move Profile Data

Is there any way for me to back up my profile data? Currently, any time I move/copy my stepmania folder I start from square one...

Ideally, I'd also like to sync it between computers, but I know when I'm getting greedy.

Profiles are saved in %APPDATA%/StepMania 5.0/Save/LocalProfiles/
The machine profile is Save/MachineProfile/
Just copy that folder wherever, and you're set.
You can put song packs in %APPDATA%/StepMania 5.0/Songs/ and themes in %APPDATA%/StepMania 5.0/Themes/ and noteskins in %APPDATA%/StepMania 5.0/NoteSkins/ and so forth.
If you're going to copy profiles between computers, make sure both computers have the same set of songs. Scores for songs that are not on the computer will be removed when the profile is loaded.

If you're not on windows, you can find the equivalent of %APPDATA%/StepMania 5.0/ here.

You, sir, seriously rock! Thanks so much!
