Editing and deleting custom groups

I created two custom groups to temporarily use for our upcoming Zoom-based speech contest. I wrongly named one and will be wanting to delete both after the contest, but I don't see the means to do anything other than create a new group. Am I missing something in the documentation or in that part of Membership Management?

Good point. It's not in the documentation.

There is an item on the Membership Management panel:

NOTE: To delete an existing group, select the group name above, un-check all of its members above, then click Save.

However, I can understand people overlooking it as there's a lot of other stuff there as well.

I'll add it to the doc.

I rubbed my eyes and found, at the bottom of that dialogue box, the NOTE text you included above. Sorry 'bout that, though I am glad that you agree that at least for completeness it should be added to the documentation. I supoose that there's no rename operation, and that to do that one creates a new group with the desired name, adding people to it, then deleting the old one.
Thanks, Jane.

I've updated the doc.

I've done very little with custom groups recently, so I'd have to say "I don't know" to your last question. The programmer would be the only one who could answer that.
