The most obvious way you can use this group is the forums - post a question, or respond to someone else's. I'm hoping this will form a really valuable list of good literature.
From there you might set up a group of people with a similar interest - ethics, for instance, or blogging. Or mobile phone journalism. Or online newsgathering.
Adding events - conferences in particular - will be very useful. Or you might organise an offline opportunity to meet with people in your area
