The solution I’m thinking about when I get 1.1 installed is to use the Welcome Pack plugin which you can use to have new users automatically added to a Group, and have a Group called “Everyone” or something of the kind.
But I’m still wrapping my brain around the way this will work, and the best way to make sure it’s all intuitive for less technically-minded users who are used to the standard bulletin-board way of doing things.
The achievements plugin is pure awesome. A truly great way to incentivize participation, all with a nice sense of humour. I’d love to a builder-type tool to allow admins to create new achievements without writing code..
