About us is a great wiki service that works with Domain Tools. How it works is that you can make a wiki description page that talks about your site or any site that does not already have an established page.
So you are allowed to have a similar pages, description, location contact, and any other miscellenous information that may be pertinent. For example I saw this about us page that details all about this site location a cool logo and so forth.
So if you are looking for a good way to SEO than check out this about us service.
