First post in this astonishing exchange. Glad to be here.
I've installed WP3 on Rackspace Cloud, under an Ubuntu Lucid installation, properly configured all the multisite dependancies, network blogs are being successfully created, data is stored in the database, which leads me to one conclusion regarding my failure in actually USING network blogs, and that that it's somehow connected to Apache configuration.
I admit I'm still slow on my Apache, but I'm getting there. Any leads you can share with me?
