I love volleyball and looked into getting on a team as soon as I got here last summer.  Unfortunately, I only found teams at one place - the University of Birmingham.  You don't have to be a college student to join, however everyone was very young.  I didnt play long because in addition to feeling ancient at age 28, it was pretty unstructured (no setters, we just rotated through all the positions...it had been ten years since I played like that).  Could just be where I'm at though, hope you have better luck!
