Such a thread may survive longer than even some of the more patient and helpful players in game ... but indeed, knowing who to ask is a prerequisite to ask and learn.
Many players may not know this forum, so I believe a source in game would be the safest; I just doubt that it can be established in a convenient and safe way. You know ... "public books" can be edited by anyone, but must be taken, so any noob can steal it, not knowing what he does.

This may be the right place to discuss it, but not to publish the list itself.
