How do users get researcher/admin access?

[lkeegan]

One suggestion:

• all users sign up for a normal user account initially
• researchers then send an email asking for access to the data
  • if granted, an admin clicks on the user in the admin interface and enables the researcher flag
• adding an admin (which should a very limited set of people as they can modify.delete all content!)
  • could similarly be done via the admin interface by an existing admin
  • or this could be only done directly via editing the users database to make it less convenient (and hence less likely to accidently make a user into an admin by accident)
