Well, perhaps I give you my account name and password for fee, and that’s it!
I've heard of people selling online memberships to places that are tough to get in to, but anyone can create an account at CPF for free, so why pay for a free membership?
Just got another spam from CPF, wanting me to pay a subscription… ah yeah, ok, sure
This
I get it now, a premium membership
Okay, Supporting Membership looks like a premium subscription.
That makes more sense (though I won't be paying for it.)
EDIT:
Bort beat me to the punch. 
now, that makes sense. I always wondered.
Vote Bort for sneaky evil genius :partying_face:
What do you get, a free CPF sticker with the premium membership?
From the mailer...
"it provides some great account perks to you like the ability to post in the marketplace, turn off ads, unlimited attachments, Supporter badge, larger avatar, and more."
Oh CPF has had those before but never really given a spammy pitch for them. There were also a few donation thingies that I donated to. It was always a low pressure thing though, so those of us contributed were happy to do so. Some of you might remember the “Sasha’s Shoes” avatar. I had that but lost it somehow, which wasn’t supposed to happen, oh well.
in the past, I would pay $5 for a 30 day membership,
which was the minimum required for me to be able to post a For Sale ad.
It will now cost me $14.99 a year… if I want to sell a light on CPF
I have not received the email offering me a discount…
I don’t remember ever having to pay to post a for sale ad on CPF as a non-dealer. Dealers had to pay and sometimes the site got after dealers for pretending to be non-dealers. I sold a fair amount on CPF and on CPF Marketplace without ever paying. But, it’s been a while since I was there.
I wonder if CPF will shrink even more now. I don’t have a sense of how it is doing now compared to back in the day, but I do see that some old interesting lights have continued to hold their value, which is nice from a certain perspective.
