mygayamateurblog.com
mygaytwinksblog.com

I would also register mygayblog.com from which I would either link to the other blogs, or on which I would show all the posts from all the blogs.

What I'm not really sure about is if it would be best to install wordpress on each domain seperately, or if there is some other possibility. How would you do this?
