That question is answered  in the FAQ at http://www.renderosity.com/mod/service/index.php?questionid=212

 

The problem is that you need to know to go to the forum to find the FAQ, you need to know that the big red thing at the top of the forum is actually a link and not a header when it doesn't look like any other link on the site, and the FAQ itself is intimidatingly long. It's a usability issue as much as anything else.

 

As Scorpius suggests, it would be helpful to have the symbols all defined on the Wishlist page itself, or even a separate line under the "Shop | Search | Account | Cart | Check Out" links, since those symbols appear on other pages besides the Wishlist page. You could even put the symbols in the Marketplace buttons for each of those categories, since each of them has its own button, and that would make it really obvious what was going on.

 

It would also be helpful to have a link to the FAQ appear in the dropdown menus, maybe in the "About Us" dropdown. As it is, I wound up having to do a Google search to find the FAQ, because it seemed impossible that a site as big and deep as this one wouldn't have a FAQ, but there was absolutely no clue where to look.
