I'm in a couple of "free" forums. In one, people kick in money now and then to keep it ad-free. We get a certain number of page views or 30 days, whichever comes first, ad-free for $7. Another group I'm in on the same platform, we get the ads, but I never see them because of a browser extension that blocks ads.
If Jacob wanted to impose some kind of mandatory or even voluntary membership "fee" to support the forum, I would pay it. i'd probably still be doing FF shops for $5 if I hadn't come here in my second month of shopping and learned it was okay to ask for bonuses. Probably 3/4 of my $8000+ MS earnings came from that one tip. Until I heard that, I thought the price you saw on the job board was all there was.
Time to build a bigger bridge.
