I'm glad you mentioned the issue with subscribing to a thread that has moved. We'll have to pass that bit of info along to the CoffeeCup crew.
Adam, I did pass it along and I am told that as long as a thread is 'moved' and not deleted and then re-created, there should be no problem. There was an issue in moving this thread that it got "lost" for a bit, so that might have caused the loss of subscription

Might be something to keep an eye on either way.
www.mainsites.ca is my website, and yes, some of it is crappy.
