well i see a few problems with your current approach.
1) as you can see, 99% of it all will be leveling requests
2) forum audience is mostly higher level players, not that many truly new players around for you to really make a difference on
3) you will get invite spammed xD

my suggestion:
1) agree to leveling requests, but only as a method to test their skills. depending on what they show, instruct on the go.
2) Face book. keep posting it. that, or go to FH.
3) make a new character JUST for this. as you reach lv20, go help FH and DF new players. at lv30, go help balefort and fathom guys. at 40, go help swamp and FN guys. at 50, go help all 3 AO guys.
4) pack a riot shield.

PS: dont get frustrated. derps will come.
