I'm a moderator of a group. How do I access the group membership list?

You should already know that, duh? 

I signed into Yahoo Groups, but I couldn't find my group. Then I used the full group name log-in and found my group. However, there was no "management" link to click. I have turned paused all the ad-blockers and privacy settings. Any other ideas?

Thanks!

go to the group's website, maybe log in, then click "management" and select "manage members"

Carol and Shannon are wrong about it being impossible, but right on the groups being discontinued on december 15th 2020

You can't. Yahoo Groups to shut down on December 15, 2020: https://help.yahoo.com/kb/SLN35505.html

You can't. Verizon cut off all access to Yahoo Groups on October 15. All Yahoo. neo Groups will become totally inaccessible on December 15 in 3 weeks.
