Home Page Title - All in One SEO Pack


I just want to change the title tag of the home page of my site. I have the Sitemaps and SEO - WordPress MU Style plugin installed and it's obviously easy to change the title of all the individual pages through the section at the bottom of the Edit Page section, which is great.

However, how can I change the title of my home page? I don't want it to just be the name of the site. I need a more descriptive title.

Maybe there's something obvious that I'm missing but I can't find it.

I'm using the bp-corporate theme in case it helps.
