You Won't See This

Yes, the problem is I’ve maxed out my server space at Salon’s host, so I suppose this means moving over to my FTP server again.
Even then, though I’ll need to replace the home page at blogs.salon.com/0001111/ with some sort of link or redirect to the new address, or it will look like a dead blog to anyone coming in from an old bookmark or link!
But how do I do that when my allocation is full? How do I clear out the remote host without killing my site?
