services diminishing, nearly had enough
We now have no access to even see the bouncing members in our groups in order to remove them, we can only chat to a so called Yahoo specialist" if it relates to abuse or spam. I have been a member of yahoo for decades and seriously, I have almost had enough of the diminishing level of product, support (or what laughingly passes for support) and quality of Yahoo services.
It's patently clear that Verizon doesn't care about yahoogroups. you may want to move to some other company, for instance groups.io
