1. For big members, make sure to stimulate some good Doctor Who discussion and post a couple of times per day in meaningful threads (so ones like episode, figure or comic threads, not games or what you're listening to).
2. For new members, introduce yourself, tell us what your favourite figure is, what your least favourite is, favourite Doctor ect. in the relevent threads.
3. For everyone - get promoting! Let's get some new members, if you're a member somewhere else, either a Doctor Who forum, Twitter, Youtube, whatever, then promote this place!
