Problem having two sites

I was having an issue a few months back with one of my user accounts, and the only solution was to create a new user. But I couldn't for the life of me figure out how to get my iWeb site to tranfer to the new user. So my workaround was to create new pages under the new user, and go back into the old user only when I absolutely had to make changes. This worked fine since November, but now I see that my newer site -- which is a subsite to my main domain -- is now defaulting as the main page on my website. This is bad!

How can I merge my iWeb sites from the two users so I can avoid this problem? I realize that Mobile Me is going away, but I'm hoping to solve this problem today.
