Ah, those three you mentioned are subscribed forums -not threads. Subscribed forums are listed in another block under subscribed threads in the User CP. If you are not seeing them, you may have hidden them at some point. There should be a title-bar for Subscribed Forums and to the left of it a little triangle/arrow. That is the show/hide toggle
And yes, the daily updates are part of the subscription. I have about a dozen forums here on Camaro5 that I subscribe to daily, and a handful that are weekly. Its quite a handy feature for keeping up with everything.
Note, if I've gotten any facts wrong in the above, just ignore any points I made with them
don't believe a thing you read about the next gen Camaro -- as history has proven time and time again:
WE DO NOT TALK ABOUT FUTURE PRODUCT PLANS PERIOD FbodFather
