But there should have been negative rating also, i suggest. -1 and -2 would be enough. Because some directories are utter crap and deserve to get a negative rating.
Linkmagnet.net is a Free PR5 directory, its pritty good but your site does need to be at least a PR4 to have any chance of being listed for free + few other rules too. Paid listings are coming soon to this site.
