How do I get all My Groups on the same "My Yahoo!" home page?

I am the moderator of 2 groups -- which I started. On one, there was a on (near the bottom of the page) that offered to add the group's page to the "My Yahoo!" home page. On the other, no such on appears. I'm not sure how I got the option to appear the first time -- I think it just did on its own. I'd like to see all of my groups on the same home page. How do I do it? Thanks in advance!
