nono. sorry, i meant blogs where i can host wordpress blog accounts. for example wordpress.com or blo9s.com. and if anyone's got a full list... thanks
Best way would be to find footprints in the template and then do a search on Google for more of those same footprints.
http://andwat.edublogs.org/ has a list of multi-user Wordpress sites. I think he also has all the ones he's seen tagged on del.icio.us with "wpmu."
