I found that just sticking to the basics at the beginning was the way to go for me because I had SO much stuff to list I didn't want to get hung up with a "what do I do now" anywhere. Then little by little I started using more features as I became more familiar with the site.
I don't even know how to use ebay's new SYI form, haven't ever tried it. (It looks like a nightmare) With Auctiva I can put a listing together in a couple of minutes and that's what I'm after

BTW, my pics load slowly too, but they always have, guess I'm just used to it

Rock Bottom Galaxy said the initial setup can be time consuming, and that's certainly true, but once you get it done you'll find it's WELL worth it.
