$15 isn't a lot to part with... Hell, I spent that this week on delrin balls... But I was flat pissed off at not being able to reply to threads that had got moved to a pay-only forum when previous non-member replies were already present.
It shoots the forum's own foot to have valuable posts locking new and old visitors out of participation.
I could surely see charging to START a thread on certain topics- like a new product announcement, or to have signature links to vendor sites, etc... But the way it is now is frustration to anyone on the fence about getting into saddle hunting and wanting to ask a question in a thread that is on their topic of interest.
Bad design drives away customers. It is a reason I haven't registered yet when I could easily afford it.
