If you really want to join the forum and contribute, a quick test on a list of rules (that is short) isn't that bad.

That may sound logical, but it would certainly affect the forum's number of new good members.
Sorry if I'm making this sounds like the end of the world. It really boils down to: Is losing some good new members worth it for losing some low quality posters? (I say "some low quality posters", because there will probably be plenty even with this system).

If you really want to get rid of shitposters/low quality posters then invite-only is the best system, but that will stop just about any forum from growing at a good rate.
