That is totally over my head. I have noticed that some Yahoo Groups don't have all the advertisements and wondered what the deal is. But when it occurs to me to go check with Yahoo to see how it is done, my eyes gloss over, and I feel a desperate need for lots of beer.
If you want to figure it out, I'm sure that we can easily vote to give you whatever moderator powers are necessary to make it happen.
BTW, I am subscribed to several BMW Motorcycle lists. The cool thing is that they are not run by Yahoo and have no advertisements built in. The bad thing is that lots of people complain about unreliability -- lost messages & such. I'm rather tired of Yahoo myself. I've seen too many groups just disappear and have to start over with a new name. Yahoo has screwed around with DMCForum a few times changing the group attributes. I think their beef was due to having public archives with too much 'adult content'.
