Transfer of ownership of usergroup for method creation in group namespace

Hi FC team,

We have a method namespace called Talkowski-SV on FireCloud, in which members of the Talkowski-Lab-SV group can create methods.

The sole owner of that user group left the lab several months ago, and we overlooked transferring the owner permissions of that group to a new member before he left.

What recourse do we have to retroactively nominate a new owner of that usergroup? Is there someone in particular I should contact? We would like to transfer the group ownership to my FC account (rlcollins@g.harvard.edu).

Thanks,
Ryan
