I added a few sites myself when I started it a few months back to make it look less lonely. Haven't looked at it in a while and just noticed that the main page has a PR4. Nice surprise. It consists of mostly real estate categories, but you can submit to the "Other" or "Business" categories if you like. Sub-categories don't have any PR, but the top 10 highest overall bids get on the PR4 main page. Looks like $2 will get you there at the moment. http://northatlanta-homes.com/helpfulsites/
Did I mention you actually get a total of 7 links if you're on the main page. - 3 links on your details page (example), 2 links on your category page (example), and 2 links if you're on the main page. Tell me what you think.
whopppss!! I submitted one by mistake, I actually thought it was a free offer! :s Sorry about that buddy
