I agree that Wikis are a great enhancement. Threads, including stickies, will remain as the main focus here, particularly for experienced Frequent Flyers. The Wikis though will provide a much better entry point for those new to frequent flying in general and FT in particular.

Take for example the AA Plat Challenge. Someone who reads mention of the challenge could:
1. Read the 100+ page sticky. Lots of information in there is no longer relevant, the information is all over the place, and it's really, really long.
2. Post a new thread asking about it. This leads to "do a search", "read the sticky", and similar remarks, but very little useful information.
3. Read the Wiki - it's kept (fairly) up to date and provides all the required information in one place and in a well-structured manner.

Well done to RatherBeSailing for taking the initiative.
