I'd suggest writing some episode guides for the previous seasons before the new season starts and getting them posted.
I skipped out on season four, and guides for the specials would end on a critical note. (Enjoyed the first one with Michelle Ryan as the diamond-snaffling minx, only seen the last 10 min of the mars one.) An overview of the RT Davies era, and some thoughts on the pre-season buzz, might be better, and keep things on an upbeat note.
Hopefully over people will have loved the recent eps to bits, and post up their own thoughts.
Doctor Who is the only cult-y TV I'm watching right now (unless people want thoughts on the Sweedish version of Wallander when it starts back up on BBC4 ) and I'll be posting on that, and hopefully some stuff for the movie forums. Some stuff in the fanfic forum as well.
Then you need to start keeping the conversation going with the new members.. whoever the admins on here are, if you do all that and then put a couple of hours a night into replying to anc creating threads on here it might just come back to life. I check everyday and I'll do my best to contribute to stuff.
