Anthony and all:
Here is a post I received from Piotr who is one of the regulars on Cybalist.  I also queried Yahoo's support team but have heard nothing.  I'll try to access PIEML and if successful will be back in touch.

Nobody knows what really happened. I've sent several queries to the Yahoo "support team", but all I got back was automatically generated crap -- no useful info. We've moved the discussion temporarily to Chris Gwinn's IE e-group called PIEML.

Dear Piotr & Glen,
What has happened to Cybalist?  Where are all the messages?
