(I am a registered, current IntelliJ IDEA Ultimate user.)
If I start with the free version of YouTrack, ...
a) will it keep what I do private?
b) can teammates who aren't JetBrains users yet be numbered among the free users?
c) is there a way to grab my YouTrack data before it's lost (like a YouTrack upgrade, or us moving to a purchased YouTrack license, etc.)"
