Hey guys,
I'm trying to scale a profitable campaign across a handful of networks, but am running into a few roadblocks. If anyone is familiar with the following, advice would be appreciated 
Millennial Media: am I able to exclude all apps or all websites, or do these need to be done on a case-by-case basis?
Buzzcity: Can I use more than 1 creative per campaign, and am I able to exclude all aps or all websites?
Muchas Gracias
