In the ad pool section next to the delete disable links, there is a drop down box with numbers in (1 to 15 in my case) what significance do these numbers have. Its set on 1 at the moment but knowing what happens if I change this for any reason would be helpfull Thanks Robert
Robert this is a ad-coop question - it should be posted there - I have moved it The 1-15 is a weighting mechanism if you have them all the same they get the same weight.
And see the sticky FAQ. The higher the more 'internal' weight you assign to it. 4 ads with 1, 1, 1 and 15 weight with a total weight of 1000 will distribute as follows: 1/18th x 1000, 1/18th x 1000, 1/18th x 1000, 15/18th x 1000
