Ummm... Can we stay on topic guys ?
Back to the topic, just adding to my tutorial above ... when you make changes to your httpd.conf, donot forget to restart Apache.
I get a lot of emails from people working with WPMU about how they get blank subdomains with an "Index of /" page... and many of them tend to forget the important part of restarting apache
Also, if you're giving FTP access to someone... please give it to someone trustworthy and check for unknown files on your folder. I am writing a script that will let you scan your server for modified/changed WPMU files and/or files unknown to WPMU. Should be done by tomorrow. Cheers
On another note, I tried the Shinoda.mike guy on DP, pretty quick fella. Paid him like 40 minutes ago, and I already see the WPMU installation up and ready with 8 subdomains. Pretty Satisfied as of now...
