Registration Required to view threads or not?

i don't require it. a lot depends on your forum goals.

my visitors can see all but my private forums currently. later on, i will probably add some members-only areas, but for the most part, anybody can read all the threads.

i run a support forum, and search engine traffic is responsible for about 65% of all my visits. having that content out there is an important part of how the site grows, and consistent with my site mission of helping others. that's my main priorioty.

i encourage registration by showing registered members fewer ads throughout the site and encouraing them to register with the welcome headers hack. i customize the message to my board's tone, and suggest the benefits of registering.
