Although it's preferable to do your editing on the RAW image, (if you shoot raw), but just as a point of interest, and to answer your query I have done considerable editing on jpg's, then having them printed, some as large as 24 x20, with no obvious degradation. I ran a test once, editing, saving, editing, saving, etc. multiple times and the 'loss' was minimal (to the eye). Each to his own I guess.
Thanks. That's been my limited experience with jpeg files edited up to 3-4 times.
