spend too much time on here and you'll be answering questions yourself in no time
btw, you probably figured it out from the info above, but basically there's two ways to refer to your website in listings.
put an "About Us" link in listing that goes to your Me Page and then on Me Page put a "Visit Our Website" link.
put a link in listing that links to the same item
Also worth noting, when doing a "more info on item" link, the off ebay page needs to provide more info than the ebay listing. reason why is cause ebay's policy of "the primary intent of the link must be to further describe the item"
and, if you use images or logs for links, logos for such links cannot be greater than 88x33 pixels.
hope all that made sense
