I'm new to osCommerce. I downloaded MAX and set it up about two weeks ago. I have set up the basic site and messed with template customization. Now I'm turning my attention to payment and shipping. I want to set it up to use PayPal. I've tried reading through some of the HUGE threads about the PayPal mod, but it's all overwhelming at this point.

So, here are my initial questions:
- What version of the PayPal mod am I currently using (I've just got whatever was installed automatically when I installed MAX)?
- Is there a newer version I should use?
- Where can I find detailed instructions about how to set everything up and test it?

Thanks.
