What's a User Connected Account (in the JSP Admin)?

Is it the same as Team Members?  I know Teams -> Accounts, though I'm unclear why it was that the nomenclature needed to change.  More generally, I feel like I'm having to infer a lot from the JSP code. Is there any sort of actual demo repo (for example, of the jumpstartrails.com site itself) populated with some very small amount of non-sensitive data?

that's what it is: https://jumpstartrails.com/user/connected_accounts.
for connecting more that 1 omniauth account to a user.

User/ConnectedAccounts are OAuth accounts the user has connected.

AccountMembers are users who are part of the account.

Take a look at the fixtures if you'd like to see some example data. You can load those into the app as well with one of the rails commands. 👍
