I think those are typical responses in the TA, a lot of guys there are not really there for training, they are simply there to furball with reduced lethality.
Would be best if on the first login, a new player was asked in a dialog "Would you like some help", at which time he could select YES and appear on the training list, or NO, and not be on the list. He could withdraw from that list, or be added, at any time. Would be neat to have that available to trainers so they can look at newer players and know it is someone who is serious, rather than radio'ing a half dozen guys who all ignore you.
It'd be cool if HT could add a 1 line comment from a player looking for training, giving a good time, and what he is looking to work on, so people willing to offer help could pick a person who is looking for something they can teach. He's added a couple of other things that have been improvements too.
