Requests to all members:
1. Please take it on yourself to keep this thread's Wiki up to date. If you have 90 posts and 90 days of membership, you can edit this Wiki. If not, you can post an edit request on this thread and some other member will do the edit for you.
2. This thread's Wiki should summarize the facts at an introductory level, allowing new arrivals to get up to speed quickly and painlessly.
3. When you follow a link from this Wiki, please check that the target thread has a Wiki summarizing it. If not, please create a Wiki for that thread.
4. How to create a Wiki is not obvious. Open the thread. In the blue bar above the first post, near the right, look for Thread Tools. Click the down arrow to pull down the Thread Tools menu. Halfway down that menu select Create a Wikipost.
5. If you are new to FlyerTalk or just new to the subject, read the target thread's Wiki first. Diving into the detailed discussion in the target thread is completely optional.
6. When you edit this or any other Wiki, please make a post to the thread briefly describing what you changed. Your post will push this thread to the top of the forum, drawing readers' attention back to it.

If everyone pitches in, this structure can work superbly to provide concise information quickly on all kinds of topics.
