What models have you suggested? I've made a few in the past, but are you wanting my opinion on what fixed-rate model he should apply or any other suggested models?
The hybrid models that include pay per activity, along with other factors that include a pay per post design with longer caps.
Combining existing posts, member activity and rates preferably.
From around the time when Stunna went to the 400 cap they still get mentioned now and then apparently looking a page back so someone must have read them or come to a similar conclusion.
