Ten Meg Limit?

I’m still not sure what I’m supposed to do when I’ve filled the 10 meg provided on the Salon community server. I’ve pruned a few unused graphics. It’s hard to believe I’ve upstreamed that much text!
Also, after publishing a copy of this site to my own host and then switching off the FTP service, my local server’s home page still shows the site’s home page as http://memewatch.com/blogistan/ so now I wonder how I get it to switch that back.
This may mean I have trouble posting today if I hit that max size limit again. I’m looking into it. Any experience or suggestions welcome.
