I want know if i install b2evolution will i be able to make the same thing like blogspot, meaning to let the user create there own blog? (like a subdomain) ex: i want to call my blog blogspotevo and when a user registers he will create a subdomain automaticly just like blogspot.com just it would be called like my domain instead of blogspot: ex: usersubdomain.blogspotevo.com.
I would recommend you blogger or wordpress. They are and will be the best blogging platforms no matter what will come after them.
