players of 2300AD; rules

Hello everybody!
Just joined the list a couple of weeks ago and was quite impressed by the
level of the discussions.

Is anybody out there playing 2300ad?  I just have the basic rules and would
like to discuss some extra rules I came up with and to hear about other
solutions...
Also... could someone explain me what the TL's stand for. In particuraly
what's Megatraveller TL and 2300ad TL (begining of star exploration, Stutter
drive)

One last question among the pbem archives I've been browsing through I came
up with to concepts I would suposse to be the same: gravitics and
reactionless propolsion.  I also don't understand why chem rockets are use
when gravitics would do the job (are gravitics range sensitive????)
