    Alex, you wrote:
    "But sometimes the beginning of a thread is in some previous month, and sometimes I have difficulties finding the beginning. Can I do anything better than search the monthly lists one by one for the beginning of a thread?"

    There wasn't an easy way to do that an hour and a half ago, but now there is. Go to the top of the NavList main page and look for the link that says "generate custom index". It should be self-explanatory. If you want all messages in a thread with a reasonably specific subject, it works fine. But if the subject is generic, you will get hits for multiple threads. For example, try setting the low date to 200101 and the high date to 201201 and in the subject field enter "lunar distances" (without the quotes). Leave the author field blank and hit 'Generate Index'. You will find that it returns all messages from about two dozen different threads. Now go back and change the subject to "Grenadine lunar". That's very specific so it returns all the messages in one single thread ...from nine years ago.
