I am new to the forum and the information is great but I am getting information overload. I am in the process of setting up WPMU in a folder in my main website in order to setup about 100 or so subdomain blogs. Does each blog formed under WPMU have it's own plugins or do they all operate under an umbrella of plugins? What I am trying to accomplish is to have some feed by the rss feed from my articles directory with a rewriter, some feed by other content generators like CC, etc based on the keyword. Any suggestions?
