How long does it take for new ads you put into the network to show up? I changed my ads several days ago but the original ads are still showing up on the network. Do you have to log in to the coop network and manually validate your sites every day for your ads to show up on the network? My master site gets validated only when I go in and manually validate it. My sites bound to the master also never get automatically validated, I have to go in and validate them. I know this because they said sites appear to be on your site 12-10-2004.
You can't flush all other people's ad_network.txt ad cache files in which (especially on lower traffic sites) your old ads might still reside.
