Free to submit your directory to criticdirectory

Hi, all!
I have over700 listing mostly general web directories. Well i have to inform you its now a "Paid Directory" cus i'm getting alot of spam links and they keep submitting the same ones over and over. The listing is $5.50 for a perment link so i don't think that is to bad, right? I personally check out the submiting links to all the directories and place them in the right categories. I spent at least 20-30 minutes before i approved each directory that is listed. I hope to add a lot of cool features later on so keep watch? Any ideas to help improvement let me know? :0)
