Sometimes I have found that I have to be the one to initiate a friendship...It seems that some of the people I felt were non-friendly ended up some of my closest friends...If when I move there is a local guild, I will be sure to try it out. Not everyone opens up to new people easily. Perhaps compliment what they are working on or ask a question to break the ice...I always figure there are no strangers, only friends we have never met (and strange people!! LOL)
