You can't force people to come and say hello, but as a community we can welcome new comers to tus with arms wide up.
Having less trolls and bitching on the forums would certainly aid in new commers feeling like posting on the forums. If there was an atmosphere that was friendly and more encouraging im sure they would.
Currently i don't think thats the case and new commers probably get some insults about their new clan or whatever.
When i was a noob and posted on wacl about starting CKC, all the pros at the time were awesome, noobs didn't get booted from games and there were more funner where they could take part in and the pros would teach them tricks in roper, or tactics in pro.
Alot of us only play league games and never aid to the development of our community. They are the future of tomorrow, just like all of you here, who have become good wormers, good into the game through kind players and a welcoming community. Pay it forward and return that favour to the new commers, we were all newbies once!
