I'm (hopefully) in the process of getting ready to install wordpress MU on my political website(http://www.barackobamaismyhomeboy.com/). I want to give the many grassroots supporters a place to show their support for their 2008 candidate, and while I would love to give them the ability to do that, I am getting a "large enough" amount of racist comments and completely unacceptable comments on the interactive pages that I have to moderate that's happening more and more frequently.
I was originally thinking I should let them have their own subdomain, but after thinking about, I would actually like to have everyones blogs under the http://www.barackobamaismyhomeboy.com/obamablog
path... so an example blog would be http://www.barackobamaismyhomeboy.com/obamablog/example instead of subdomains. Does part of the MU setup let me choose whether they use subdomains or just a folder on the main domain?
Since I get so many questionable people on my site, is there a way to add "rel=nofollow" to all the blog posts, blogrolls, links, and any MU links? Would this be editing the themes, or is this some internal server issue... with .htaccess, etc? I hate to do this, but I can't moderate everything that gets brought up. Politics is a sticky topic and the last thing I want is some immature person abusing the site. It's only going to get more time consuming as the elections get closer.
