Hi Scott.  I was wondering where the addition of comments and ratings might be on the todo list.  For me, it's the enhancement I'd most like to see.

I actually did a cool ajax song rating module recently.  The idea was we could use it to generate a playlist of favorite songs for a DJ (I'm running a site for my high school class's 20th reunion).  Using that experience I might take a crack at adding the ratings and comments to my local install of simple gallery, but if it's coming up I'd probably hold off.

Thanks for all you've done and continue to do.
