it has been around 15 days that i have signed up for yahoo publisher .. but it is not sending a email weather my account has been approved or not !! why ??
Ummmm....I think you posted this in the wrong forum. This is the Google Adsense forum and not the YPN forum.
I would not worry too much about it.. YPN sucks, they can't deliver a targeted ad more than twice in a row, and it's run by a bunch of idiots... and, unless your niche is one of the three that they have ads for, you arent going to make any money from them anyway.
Expect to wait for months for an answer. Some get a reply sooner but a few months seems like average waiting time for a reply.
No, it's just that they really can't seem to figure out how to get their act together.. have a look through the YPn forum and you'll see.
