Only online. I have a few friends that will correct me when I'm
  wrong about something, or debate in groups, or fill in some gaps
  here and there. But most of my study has been self-study. I'd
  love a brain scan or two of course; but I'm ok working it out
  this way for the moment. One day I'll probably want one once
  I've exhausted this portion of research. [which means: get bored
  with it tongue emoticon ]
