You do know that wordpress and wordpress MU have been merged started with wordpress 3.0 ? You just have to install normal wordpress now and make a change to config file to enable multi sites
It's simple to upgrade your blog to a "network" the new term for MU. However you must know, not all plugins are compatible with networks, google sitemaps is one of them.
yes ,but plugins I want to use don't work with WP 3.0, and who knows how long till updateas on plugins
I have already hired bordot for the job, he did a really good job Thank you everyone for your inquiries
