Re: newbie needs help
Also keep in mind that if you "hide" spreadshirt's URL when the domain forwards, (using stealth forwarding or domain masking or whatever the place where you registered your domain calls it) it can sometimes mess up the functioning of the shopping carts for customers using IE6 with the default settings.
I don't know if this is true for spreadshirt's shopping cart, but it has to do with shopping carts needing "cookies" to be set to operate and the fact that IE6 doesn't allow cookies to be set for "third party" domains in the default setting. Third party meaning, if your domain is duckpuddle.com and you forward it to spreadshirt.com but "hide" the spreadshirt.com domain name, it actually loads the spreadshirt domain in a "hidden" invisible frame and the cookie would be coming from spreadshirt but IE6 thinks the cookie should be from duckpuddle.com
That's probably more explaination than you needed, but it may be something you want to ask in the spreadshirt forums to see if it might be a problem.
It can also cause a problem with the SECURITY lock that shows up in browsers. If your domain is showing instead of the spreadshirt, then customers might not see the important security lock when they check out.
