i use them alot. i have about 20 different sies that i do it on. i was wondering how many others take advantage of them. the ones i do are 1:1 or 5:4. there is a full list of them on i have gotten some good referrals from using them too. what sites do you use? do you just skip them and not mess wth them? do you consider them to be a waist of time?
