I've had some, but not a lot of clicks from an account I opened with Looksmart's LookListings. I am about to cancel it, but they state that the site will be removed from MSN.
Prior to signing up with them, I got lined up with the microsoft affiliated submission site. There, they say that my site is re-indexed every 48 hours, and picked up by MSN.
So, will cancelling LookListings, which has not done much, create big problems?
