Small signature ads are obivously less effective, if useful as all. Only senior and hero members are worth the bother, may be full members aswell to some extent.

From a business point of view, Stunna should just offer a higher rate like 0.0006 for senior and hero members, may be 0.0001 for full members, and that is it. This will reduce potential ad space for other campaigns, reduce overall campaign costs, and a lot less work.

This would mean loss of revenue for most of the members here, and may be my future revenue too, but this a business campaign afterall. Think of the revenue in the past as a bonus, not a inherent right on the forum.
