Once your forum gets popular, you'll find more troublemakers - people who make obnoxious, obscene, or rude posts, for example. All kinds of trolls, too.

Without registration, it's easy to switch or disguise identities, too, or even pretend to be someone else. Registration eliminates the false identity problem, and slows down those who would keep posting under different names.

Run without registration as long as you can - when the problem levels get frustrating, it's time to implement it.
