Normally when I see a new player I run up to there avatar, do /love, than run off in a way our heads touch so it looks like I am kissed them. Actually I do this to pretty much everyone. . . .
Normally I help new players with builds on there servers and show them new approaches to what there doing. Like this one time a new player came on my server (not his but same thing) and he said he was an eventer. He tried to make a default randomizer but had problems setting it up. I then showed him how you do it with projectiles instead of relay and how it needs to have multiple targets instead of just one. He was a nice guy :)
