Hi and sorry for the delay.
Users cannot really be deleted on Rancho as that would imply some
changes in the database regarding the objects that are connected to
that user (like messages, etc.).
So, what can be done is to disable a user. That's done on the "People
and Companies" area that can be accessed from the Dashboard.
Let us know if you have other questions.
Best Regards,
