I just finished an oo framework that I started over 6 months ago, and I wanted to just announce it to you guys and see what you think. It basically encapsulates the basic functionality an average site makes use of such as database/file abstraction, user management, session handling, validation, etc. It's not what I would call stable since I've only done preliminary testing, but it works well. I plan to use it as the core of all my future scripts starting with a complete rewrite of myimgs.com. I'll definately be testing it for bugs and possible optimizations.
If you think you could make use of it, I'd appreciate a userbase of more than the 5 or so it currently has
