Wow - thanks everyhahahaha. The search function allows the user to filter by Premium, Free, AVS - so that may mean some extra traffic to your free sites.
To get the search function on there, I just had a programmer mess around with it for a day or two and did some formatting of the results. It wasn't anything that hard.
Over time, I plan to tweak it more so it has an algo more like google. My database of links is starting to push the 10,000 mark, so there is plenty to search through.
Keep submitting your *good* free sites - we review every day.
