I've only been on for 4 mos, so the newbie phase is still fresh for me. I have a couple suggestions:
1. Vets need to continue to be welcoming. "alt-f4" jokes, which come from a minority,
SHOULD BE QUASHED WHENEVER SEEN (And, no, I never got caught by that one.

)
2. The "ask for training" interface in the game needs to be tuned up. I never was offered training despite "requesting" a trainer, and once I started checking in to giving training I could see why.
A) Many of the "trainees" in the selection box don't even know they're in it -- and have progressed past wanting it. HT, put in a window so newbies are prompted to respond about desire for training when they log on; when they chose to do so, start prompting "do you still want to request training".
B) When a player requesting training logs on, how about a ch200 message saying "a player requesting training has logged on"? When the MA has been boring, I've at times looked for somebody I could teach starting game mechanics -- but couldn't find, as all the green names in the box didnt want training. I've had to watch 200 for newbie type questions, then PM an offer to train.
C) And while we're at it, the trainer dialogue box is just acting, well, weird. When I adopted somebody, I ended up with my name in green on the right-- even when I had been playing for 4 mos. How about letting a player who sees his name double click on it to change request status?
3. Teaching should have a curriculum -- trainers should know to start with game mechanics, move to energy management, etc. Some of my teachers have started with, "so, what do you want to know?" While I had been exposed to Shaw's book, and had enough background to know what I needed, many new players are going to say "I want to fly good." Theydon't know what to ask, needing help even with that.
The majority of vets are welcoming, and willing to teach. There are a vocal minority who seem to go out of their way to put down or taunt newbies, on 200. The mature vets should really be proactive about scolding the jerks, and intercepting the Alt-f4s!
