User and group removal ?

Hi,
I am just starting out with OMERO and looking at the administration side.
I see commands to create users and group but I don't see corresponding command to delete/remove them.
Is there some data integrity/retention reasons behind this ? Or have I been looking at the wrong place.
Cheers
