At the top of every page, just before the first post, are 4 boxes on the right-hand side of the page. These are drop-down menus.
SAVE - THREAD TOOLS - SEARCH THIS THREAD - RATE THIS THREAD
Click on THREAD TOOLS, click on 'subscribe to this thread'.
This takes you to a page where you can 'Add Subscription'.
This will save the thread to a folder which you can access from your control panel - USER CP.
Once in your control panel, there are a list of functions on the left side of the page. Scroll down to "List Subscriptions".
Click on it to open the folder containing all of your saved subscriptions.
I'm not sure how many threads you can subscribe to but at least your favorite threads will be saved until a time when you can 'copy/paste' the pertinent info to a folder on your PC.
Once copied to a folder on your PC, you can delete the subscribed thread from your AZB folder.
