I have been negligent in unsubscribing to threads that no longer interest me.  
Most are dormant, but I’m thinking that they waste space in the database.

Any quick way to unsubscribe from all, rather than doing them one at a time?

Thanks in advance.

Go to [this link](http://boards.straightdope.com/sdmb/subscription.php?do=viewsubscription&folderid=all). On the right side of the thread list you will see the word “notification” with a check box next to it. Checking that box will select all the threads, and then you can select “Delete Subscription” from the drop down box at the bottom right of the thread list.

(Thought this post went through the first time, but apparently not.)

If you are receiving thread reply emails, each one should have a link at the bottom that says click here to unsubscribe from all threads.

Do the subscriptions really take up a lot of database space? Should I delete some of my 570+ subscribed threads?

If I was doing a table to track subscriptions, it would be (User ID, thread ID), and each of those fields is currently a 5 or 6 digit base 10 integer. So at most you’re using up 12 bytes per thread, and probably 2 bytes of offsets. For 570 threads, you’re using about 8k. I wouldn’t worry about it.
