Sweet. Let's consider that point settled. > >Also, I strongly support displaying it publicly that way "we only >charge >if the fee to processor is less than 10% of the total". I will admit that the argument about sudden fee changes is a bit weak. But I'm curious; what is the benefit to displaying a percentage that makes you strongly prefer it? I still think a level of indirection is a good thing. It almost always is in software. _______________________________________________ Discuss mailing list [email protected] https://lists.snowdrift.coop/mailman/listinfo/discuss
