Remember: Most people here are strangers to one another, or were before they came to play together, so you are by no means the "odd man out" that just joined a tightknit group of friends, as it's often the case in real world D&D games. Here "not knowing anyone else" is more of the norm than the exception. Sometimes a few players or the GM might know each other already from a different game (I'm for example GM a game and one of my players started one of his own, and I and another of my players play there now - with a bunch of more strangers that none of us knew before). Sometimes two people know each other in RL and join a game together. Very rarely you will find a group where a real-world group moved to Roll20 (maybe one of their numbers moved away or so) and you actually are the "odd man out" because 4 of the 6 people in the game live in the same town and have been playing together for 15 years. That can happen, and then it feels a bit odd, but that is the absolute exception. But I can understand where you come from. God, I remember when I was about to host my game here, I was scared, cause I knew nobody. Took me a week or so till I finally posted the LFG ad that I had finished writing long ago. :) It turned out well and I had a blast since.
