I prefer to welcome people when I see them post in a thread I participate in, and actually contribute. I'd hate to pat someone on the shoulder and give them a tour of the boat only to realize five minutes later that they're one of the ten year olds who think the best way to make a good first impression is to start a thread in the SH5 forum going "
hi all this game lol kthxbai!"

.
Those I'm happy to see, however, get a "Welcome aboard from me".
