Well man first off, most of us make groups of sites at one time like 6-10 its way to much to ask for us to have to send you new sites every day. If you want to space them out then that’s up to you, I am also assuming you can not really send much traffic back. You should really try to make it as easy as possible for other webmasters. I would try it out but I require return traffic for me and the other directories I trade with, and 1-3 clicks a day are not really going to do that for me.
