I'm running/experimenting with the new WordPress 3.0 Beta and am trying to set up a multi site blog system with each individual blog, having it's own domain like domain.com (no subdomain or subdirectory).
My host doesn't support wildcard DNS, so it's set up using subdirectories. My host won't allow me to put in an "*" in the A-Record as described in the Domain Mapping plugin: http://wordpress.org/extend/plugins/wordpress-mu-domain-mapping/installation/.
What should I do to make newblog.com point to oldblog.com/newblog?
