Accidentally deleted my "web.mac.com" Welcome

Was fooling around with my blog stuff, didn't like the Welcome.html page so I deleted it. Now I want to replace it with something new, but can't figure out how. It looks like I deleted my whole site!!! When I enter http://web.mac.com/my.name I get this big alert saying "We're sorry but we can't find the iWeb page you've requested. It's possible that:
· The address was entered incorrectly. Check your spelling and try again.
· The .Mac member of this name has either created a page and removed it or has never published an iWeb site.
· There is no .Mac member of this name. If you'd like this member name for yourself, sign up for a .Mac account right now and have your own iWeb site in minutes.

Can I get my old address back or Am I just out of luck?

try just publishing your site again

Been there done that. You did delete it. But like podraig suggested, if the page is still in your iWeb application (not to be confused with the iWeb site), just published the site again. If not, you need to start from scratch.
