The top forums on the Internet seem to have wiki post options. This enables threads like hotel master threads to have summary information that everyone can edit so you don't have to read through dozens of pages.

I'm sure this doesn't require an example, but here's what inspired this post: today I wanted to post a document containing Starpoint Instant Award options for a specific SPG property. All I can do is post it, and if someone could use that info, it will eventually be buried on page 14 or something. If there was a Wiki post, I could post it there and folks could be able to read that with other essential info easily.
