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 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?
