That's good news .... although the e-digest will not tell you when there's been a post to this thread. It gives you the new threads with a lot of activity from the previous day.
There's somewhere in the settings that you can opt for the auto-email every time a post is added, or not. This sets you up for all the threads you post to. Plus I think there's an option for that auto-notice to be all of them only once a day and perhaps once a week too?
For one thread only, go to the line just above the first post on each page of a thread, on the right side of the page. Click on Thread Tools. Then Click on Subscribe (or unsubscribe if you're already subscribed and want to stop getting the auto notices).
Maybe someone more "geek-ified" will come and help you out?
Happy New Year, Pardners!!
Yeeeehaw!!!!!
