Im just playing around with WPMU right now and I got it installed on one of my servers running H-sphere but I'm having a wildcard issue... I assume that I just have to get my host to enable this but Im wondering if anyone is really running a lot of blogs and using hsphere as opposed to cPanel etc... Its just a little test server that I run as oppose to my dedicated servers which all have cPanel but still, Im interested in feedback from you guys. Also, anyone running multiple domains on WPMU? I know this can be done but Im unsure as to the best route to take.... I would like to have roughly 500 domains all be controlled by one install of WPMU... any suggestions? Thanks DP'ers!
