I skipped the GT230M since the "M" means mobile and laptops may overheat when crunching with their GPUs (although I do with mine) but I did contact the others.
Maybe we should skip the "new users" thread on this board and send out a private message to each new user to their user account on the project in which they joined the team (e.g. if a user joins PG, we send him a message using the PG message board). While a little more time consuming, the personal invite to our boards here may create more active (and credit whoring) members.
