I'm trying to activate multi-site on a new install of 3.0, modified the config to allow it, and all seems to work well. I have all my wp-files and directories at the root of my domain, and want to use subdomains for the additional blogs I'll be setting up.
For some reason, my siteurl needs a "www." in it in order for me to log into admin. If I leave it without the "www.", I'm stuck in an infinite login loop. If I change the WordPress address to match my site address by adding the "www.", then the Network config page tells me the www. is going to be part of each subdomain (ie. blog123.www.astreetproductions.com), which is a little counter-productive. Am I doing something wrong?
