Thanks.
I think you came here under a misunderstanding. This is a forum for Bitcoin and cryptocurrency enthusiasts to discuss relevant topics. Being able to sell your signature space to advertisers is a privilege that many of us are able to participate in if the advertisers feel that our posts are likely to gain a significant number of readers. If you came here looking to join a signature campaign that's fairly unlikely to be the case.
Thanks. I was pointed in the direction of this thread. The mechanics as such were not explained to me. Bitcoin something I am keen to learn about, it is just starting somewhere.
