User Problem

Right now, there is no user-specific audit log, so there isn't a great way to determine when users are added/removed/updated.

Suggested Solutions

Adding a user audit log would be great. A tab on the user similar to the activity stream on the teams' pages and a users added/removed log should cover most things.

Current Workarounds

If the user was added/removed in the last 13 days, the info will be in the debug logs (Settings > Logs).
