I really don't know what is your basis in accepting but I did sent you a pm, reply atleast please. So I am not left wondering why others is accepted.
First of all, it is not very polite to be posting these issues on the signature campaign thread. Secondly, If you have already sent him a PM, wait for his response instead of being impatient and writing on this thread. Thirdly, looking at your previous 20 posts, you pretty much just post in the services section and in twitter and signature campaign threads. You really should be posting in multiple sections of this forum as that is one of the things campaign managers look at. Lastly, Yahoo is the manager of the campaign and he gets to decide who does and doesn't get accepted. If you didn't get accepted, don't be discouraged by it as that will get you nowhere and instead keep making your post quality better and apply for a different campaign.
