Unofficial Forum FAQWarning: This is not a substitute for the manual or for searching the forums, but a supplement. Hopefully it will point you to some helpful discussions without having to find the correct keywords to search for.
This is basically a stopgap until we have a functioning wiki, and might make a good start as to how to organize it. Since development is happening so fast, information in the manual is useful, but can be supplemented by discussion on the forums, especially depending on what version you are using. This is not a complete list of the incredibly useful information that is in the forums, so if you can't find it here or in the manual, search the forum or ask
If you know of a useful post that is not here, post to this article or PM me and I'll update it.
