Welcome to WebmasterWorld Guest from 184.108.40.206
The problem I keep running into is when Advertisers run out of money and their links go "down" and are useless. Seems the advertisers need to be on auto-deposit to prevent that from happening and a lot of them aren't.
A couple of advertisers I have run into aren't tracking properly either.
Overall though it's not bad IF they pay on time. We shall see.
