they are still there, I just checked. I never use the Yahoo Web site to view them though, I get them via email.
I have noticed that many of the posts come in via email out of order lately, or I never get them.
Also- Yahoo did a major overhaul on the way their GROUPS site looks.
Have you logged in to
http://groups.yahoo.comand then looked on the left side for a list of the groups you subscribe to?
Also- there was a major outage of internet services for some big players recently, this could have affected Yahoo and your attempts to log in.
