ANSRVR currently retains groups unless you manually do a delete group, if people could check to see if they are the only member of a group, they are not using and message me directly or via the aprsisce-owner yahoo link I will attempt to clear them out.
It’s a bit of a pain but there you go.
List of groups here if the screenshot makes it through
