I've started a discussion group on facebook - in for a penny, in for a pound (good thing Great Brittan didn't sign on to the euro or this cliché would be passé). Check it out.
You will need to have a facebook page (or create one if you are so inclined) go to groups and search for "First Baptist Church, Derry NH" This is an open unmoderated group (though I can delete inappropriate posts) that could be a tool for witnessing, descipling and debating with the facebook subculture.
