e.g. you have the Engage Users groups because you have Eloqua Engage License. :-)
As Kenheung already said, you have a few more user groups available because of your license.
The overall document is still valid. However, I do agree with you that it could get an update related to the Engage user and Profiler user.
PS. can you please change your username to a more personal one? Oracle unfortunately generates a generic username when you register. How to change a Display Name
Thanks for the feedback - we'll look into getting the spreadsheet updated with this.
