Welcome!
I, too, have recently de-lurked after having hung around for about 6 months. I watched the series from its original broadcasts on ABC and hung around the chatrooms briefly at the time. After a few years hiatus, my sister got me to watch again. Since then, I've been reading quite a bit of fanfic and reading these message boards.
Maybe someday I'll write some fanfic myself if I have the time. I have one story half written but then got writers block.
I'm 36, seemingly among the older ones here, working as a software engineer.
