I think it's a common problem, one of my guilds has addressed it in meetings so many times but it still happens! There just isn't a lot of time to make friends in a guild meeting, but being nice to the Newby is a must! Join a smaller friendship group, you can't fail there. After over 15 years in my guild, if my friends (from my friendship group) aren't there to sit with, I feel like the newby!
