On other boards I'm on, you can set what kind of thread emails you want by default. I would love to have Instant Email Notifications automatically checked for each thread because I can't remember to check it myself. I can't find how to set that! Help!
To set the default: User CP/ Edit options. Middle screen there is a drop down menu for message notification type. It will then always default to that.
To change how you want any individual thread handled:
Top of the screen, with UserCP FAQ etc. Click on Quick Links.
You'll get a drop down menu, click on Watched Threads, third choice from the bottom.
The change ability rests in a drop-down menu at the lower right of that page.
