I am checking out some free code right now from ActiveForum or as it is now known Buzz Company, course now they make you pay for the complete solution (like Bondware). Looks pretty good. Thinking about augmenting the whole shopping cart, library and advertising sections. Integration. (Had a little problem with a guy who put a program on his workstation which started entering the wrong data into our client's e-commerce databases. Had to reverse engineer it and actually made it better. So while I am in that mode, I figured that I would delete half my site. Woohoo!!)
