I am new to the whole blog landscape though I am in IT industry. What I want to do is to create a web site http://www.my-future-site.com that allows people to register and create their own blogs. Something like http://www.wordpress.com itself. So I can have User1 who has his own blog site as http://user1.my-future-site.com. So on and so forth. Also User1 can invite other users to edit his site, which is a feature of wordpress. So a small company might come to my site to a blog http://Company1.my-future-site.com and have all its employees to contribute the contents. Very much like a concept of Group. Currently I am looking into Yahoo/Wordpress package. Can I do what I want to do with Yahoo hosting? I read a article comparing all blog software http://www.asymptomatic.net/blogbreakdown.htm. It said that the max. number of blogs for WordPress is 1. I am confusion with its exlaination. Can someone advise?
