Is there a way to tell THE DATE you joined a Yahoo group if the group does not show member info?

Question

I coudln't figure out a way to clarify my previous question. I know how to find out what groups I belong to. What I want to find out is what DATE I became a member on. In the groups that list member information, that information is listed there. But if the group does not list member information, where can I find out? (I can figure out when the group was founded, just not when I joined!)

Answer 1

I've never seen another was to see the join date other than on the members list- sorry, I think that's the only way to know is to see the members list
