We have a forum where people can post their questions if they get stuck in the games: The Padawan's Lounge (
http://www.lucasforums.com/forumdisplay.php?f=523).
The present forum is for the discussion of an eventual Kotor 3 :)
You are welcome to answer the questions that are asked about the games over there and discuss kotor 3 over here.
We also encourage members to post their questions in threads with descriptive titles like "stuck at the Telos Academy" per example rather than having a single thread for all questions: it's more practical when using the search engine ;)
You'll find the forums descriptions on this page:
