Mark Niemann-Ross of Adobe has generously allowed us to use the scripting section of his developers' wiki as a scripting FAQ. So, I've seeded a few pages (in the JavaScript section, of course) but wikis are communal efforts, so everyone is invited. But please don't use the wiki pages to ask questions; that's what these forums are for.
The discussion pages on the wiki can be used to asked for clarification of a page, but even then, you'll probably get a faster response and a bigger audience by asking here.
The FAQ address is listed in the Useful Resources space of the forum main page, as well as here:
http://www.niemannross.com/developer/wiki/index.php?title=InDesign_Scripting
To contribute to the FAQ (as opposed to just reading its contents), you'll need an OpenID. Took me a while to work out how to do that. What I did was go to:
http://getopenid.com/
and create an account. If you want more background information, click the 'What is OpenID' link on the left panel of the wiki.
I look forward to seeing people at the wiki and hope the content proves to be useful to everybody.
