I of course speak of requiring visitors to pay for registration. Not too long ago I released a mod on vB.org that does exactly this (look for LancerForHire - Paid Registration [and Anti-spam!] on vB.org), but it made me think... Why isn't this used more often on different software? People like to say "It's not right to charge my members for registration" but we all know it is a thinly veiled excuse for not having unique or valuable-enough content and context.
