The latest Push is currently beta, I'm looking for as much feedback as I can get as far as options to add, problems to fix, etc. I've spent time testing, but now I need some feedback from someone who hasn't seen the insides, and is going to install from scratch. Please don't let this scare you off, the code is well written (if I do say so myself), and it really handles uploads well ;-)
Version 1.0 is very stable, but the beta versions generally have more/enhanced features.

Last major release: Version 1.0
Latest beta: had a serious bug, check back soon for push-1.03beta
