I used it for a while then they implemented a sign up policy that took FOREVER to activate the plug in. Then the spam came raining down! This would be an absolute must have plug in if it wasn't for the spammin' bas*%$#s that are on the back end of it.
Sucks that a great plug in is turned to crap like this.
Personally I don't think the value is anywhere near worth the spam you get.
