How do I find group leaders?

I can see a leader's name displayed in her emails to the Yahoo group. However, there is no email address displayed.

And the buttons to mail individual a response does not work. For that matter, the button to email the group a response doesn't work either. Just the button to post an answer from the Yahoo Group site works.

There used to be a way to do this from the Yahoo! Groups pages. I see the Help Yahoo! advice below which answers my question, but I need the permanent functionality from the Yahoo! Groups added back.

Isn't there a way to get there from the Groups home pages?

I'm on a lot of groups. Removing the way to get information from within the Groups home page is a poor customer-focused approach taken for the August 2013 "upgrade".

RE: Yahoo Groups! roll-out August 2013

I went through the Google Chrome testing for updates when the problems appeared following the roll-out of the Yahoo! Groups upgrade. It's up to date. It's not Google Chrome. It's that the Yahoo! Groups buttons are buggy. I can read the script and they are wrong. I can also read about the same issues in a consolidation of issues unresolved for Groups due to this upgrade. Problems are being fixed one by one, apparently.
