What's your "Update your browser" script?

Just looking for some opinions. I've been using Push Up The Web for some time now, but it's not actively developed. Going by the original js version, the repo has been removed - the jQuery port hasn't been updated for 2 years. Is it just because it's stable, or it's just been forgotten about (his forum is still active)?

I'm on the look for something that is more actively developed, or is it not even worth using something like Pushup?

I don't support IE6 so I'm more looking for a global like Pushup, IE7+, FF3+...that sort of jazz.
