MaciekA,, I think you make very good points in regard to the tools available to us. This bb has been the standard format for years in regards to hosting, but if there are better tools, then we should use them.
However: The issue is that many hosts do not own the field they are hosting on. As such they do not collect any money for themselves. I have hosted at finchs field and flagraiders, and I (as I suspect many other hosts) do not make any money from game fees. All of it goes to the field owner and as such hosts have little control over modifying the prices, so incentives become problematic.
