From a vendors point of view:
I appreciate the opportunity to showcase my goods within the rules Dave has specified. I pay for that right and try very hard not to abuse it.
IMHO, anyone who accepts money for their work is a vendor and should be treated as such. The gray area of a hobbyist who takes on projects for payment needs to be addressed plainly. As such, I believe that anyone who accepts payment for their labors, hobbyist or professional, is a vendor and needs to be labeled as such. However, the hobbyist who makes knives as a pure hobby, accepting no commissions from forum members, is indeed different and the rules need to address their work.
On another forum I was belittled by the owner for what he called my passive marketing. I pushed the rules a little and was slapped so rather than pay his enormous fee for a miniscule rotating banner, I stopped posting there altogether. Daves fees are fair and the rules, as I understand them, are plain.
My 2 cents worth. I'm sure Dave and the moderators will come up with some tweaks that will help us all.
