Just like nb, I don't use fb.
This forum is the only place I interact with the other X fans. There are so many members in this forum, but as you can see, not many members comment on any threats. I don't want to sound negative, but I think it will be a difficult and long road for you to have a big community. I think the best way to get to know more X fans is to organise a meeting whenever there's a X function, you may get to know more X fans. I got to meet 3 members in this forum from 2 concerts. :-)
