I'm not arguing your point at all, Don. I agree completely that, as a businessman, $75 a year is a cheap price to pay for constantly updated exposure to the large audience that BF provides. A knifemaker sure as hell won't get this exposure at anywhere near that price through any print literature or at another website.
While it will be disappointing to some (including me) to downgrade a membership, your point is entirely valid that there is no need to maintain that if one isn't selling. I will still know my level of knifemaking skill, and having Knifemaker under my name won't change that. Not to mention, at this point I could give a sh!t less what anyone else thinks about that.

By the same token, I hope folks will understand that those of us here just for the fun may feel it inappropriate to suddenly pay a marked increase to support others right to sell. If Spark had simply said, "Forum costs necessitate a marked increase in membership rates to support its continuing function," I would probably go along without a second thought. However, since it's been tied into a benefit I do not derive, it makes me pause to consider whether I want to suffer additional "premiums" to support other people's income.
Tied into my thoughts is the fact that, for a number of months now, my access into the forum has been drastically slowed. I can't begin to count the times I have clicked on my BF link only to have the screen time out after 2 minutes because the forum was overloaded and inaccessible. Or, write up a post only to have it spin its wheels and time out without posting. Very frustrating. Despite the changes in last week's updates, I am still experiencing this at times, and twice today already. I know it's not my ISP or computer, because I can cruise everywhere else on the 'net with ease.
To be honest, my decreased participation and this difficulty with access already had me questioning whether I wanted to renew in November.
When I'm told that I would have to pay more because of selling issues, that adds another dimension to my determination.
I say all of this without rancor. I have lived long enough to know that everything changes. Everything, including me. I am happy to see so many people learning here and developing to the point they can sell knives where they learned. I also understand the increased traffic necessitates costly upgrades and thus a need for more income from membership to support it.
