Brains working towards machine consciousness

Platform

We (I) have pretty much decided to use Drupal as the platform for our Virtual Research Environment. The number of excellent plugins for it mean that making a feature rich social networking site should be relatively easy. I have some concerns about the differing rates of upgrades, and I am also aware that politically within the institution there is a tendency to prefer 'paid for' software – but the power and flexibility of the system is hard to argue with, in my opinion.
