I have no idea. I don't subscribe to the digest. I find digests to be way more trouble than they are worth. If you change your setting from digest to individual messages, you can just reply to a thread by hitting reply. Nothing more fancy than that. > The only URL I have for posting is: > sqlite-users@sqlite.org That's all that we all have. > > Is the trick to make the subject lines match or something? Nope, there is no trick at all. In fact, the trick is to not use any trick. Just hit reply. In fact, don't change the subject line just to start a new thread. That hijacks the thread and messes up the threading for others.
