If you enable the Changelog feature for your list: * Change-Log = Yes you'll create a log file which records all posts and subscription changes for your list. This won't do you any good for old data (the log will only start recording once you enable the feature), but it will provide you with the data you want in the future. A sample: 20011128111933 SET [log in to unmask] NOREVIEW 20011126135749 POST [log in to unmask] Emergency Virus Alert The list owner can retrieve the changelog file with a GET command: GET LISTNAME.CHANGELOG Hope this helps. -- Liam
