I agree with LoyceV, raising the rate will not make any difference as the objective is to advertise within the forum till the 31st of December. Fighting over the rates and trying to make their respective Signature Campaign better than the other is an insane approach. Both of them knew that these mixer campaigns would eventually end by the deadline. I went through the discussion on the campaign thread and I feel both of them should calm down and move on.
It won't make any difference surely for the mixers but it would for the campaign managers. Till now CM was the highest paying signature campaign but now the crown goes to another campaign that's paying $10 a post. That would at least make it as a saved memory because someone was paying $10 per post to the members and that's an insane rate. I know that within short duration of a few days the advertising won't reach its goals but still it's something unique and has never happened before.
