Thanks for your reply. Yeah, I like Ubuntu Linux myself. It’s cool you’re a linux user. 
Anyways, what I’m looking for is a little different, I may be wrong about the term though. I thought “hooks” referred to the following example: add_menu(‘profile.php’,…, ‘my_function’); In other words, I want to add my own functions and code when events happen, like say, when an item is put in the cart. I hope I haven’t muddied anything up. Anyways…
I also had a question about how to add Google Checkout. I can do the code, but I’m not quite sure exactly where to connect it to. If you could give me some pointers that would be great. I can also share this with you guys for free, if you’d like. I’d appreciate a little props though. . No biggie though.
Thanks again.
