Confirmation of availability of old format mailing list

1. Start Google Groups (if keio.jp authentication appears after startup, authenticate and start).
   
   
2. A list of groups registered for use will be displayed.
   As shown in the red frame in the figure, groups with "@ml.keio.jp" in the group description are using the "@ml.keio.jp" address (the old format list). The blue frame is the corresponding new format group (which will be the address to be used in the future).
