I have a blog amblogger.com the thing is that this blog is on anything and everything...! I have different categories in that blog.... So I want different categories on different sub domains, I don't want the sub domains to redirect to categories... I want the sub domains to be integrated in the blog...!
did you check this: http://webdev.casualgenius.com/projects/wordpress-subdomains I just know it, but I never have a try..........
