Hi James and welcome to SaleHoo,
Definitely in the right place to learn about ecommerce. I would suggest reading through our guides that you'll find under our Education Tab in the red title bar above. The forum itself carries a wealth of information, so browsing through that will net you a lot of knowledge.
Any specific questions, just post them here in the forum and you'll find that other members will be more than happy to help you out, as well of course as our SaleHoo support team.
