This is a bit of a suggestion in a couple parts mainly aimed at making the new player experience a bit more friendly.
1. Get rid of Neutral/Omni/Clan Newbie OOC and just make 1 'Newbie OOC' channel.
2. Extend this new Newbie OOC to level 26 or even level 30. I'm suggesting a higher level because it is really after players are done with the subway that they really start asking a lot of more in depth questions.
(Here's where the actual work comes in)
3. Allow players to apply to be Newbie OOC Mentors. Basically, doing so, would allow them access to Newbie OOC on all toons on their account(s) (or if this is not possible, have them provide a toon list when they apply). The application could be a few simple questions (i.e. why do you want to be a newbie ooc mentor?) and you could setup a forum area similar to the bug/exploit forum section for application submission.
Giving new players a 'safe' place to ask questions to people that truly wish to be helpful can only be an overall win for the game. Right now, the few newbie inquiries that we get often get lost in the bickering and trolling in the normal OOC channels.
