This one's hard, as everyone is really serious and helpful in the bean bags in general. As most of the obvious ones are already nominated, I'll throw out two more for the listing.
D&P3 has offered a friendly word in almost every topic in the bean bags, so props to him for being a nice guy. And then, almost surprisingly, DrSword has been showing a more emotional side and helping out in a number of the threads. Definitely gets a nomination for that. <3
