Absolutely brilliant and simple to implement and use plugin! Well done! :)
But I wanted to ask if there was a "simple" way to reset the ID numbers for campaigns used?
I hardcoded them all, according to different places in different sites, and on one of them, I mistyped something, deleted it, and wanted to re-add it, but it would only allow me to add it as ID2...so my first shared banner placement between 6 sites, cannot really be used anymore, unless I change all the setting to use IDs 2,3,4,5...
That would be great, thanks! :)
