Topic Subscriptions Not Working?

I'd love for them to have some means of unsubscribing to a topic. There's a menu at the top of the topic called "Topic Subscription". Clicking on it only has "you are subscribed to this topic" How about a switch here so one can unsubscribe from the topic. I searched the site for "topic unsubscription" but coudn't find anything.

Gallienus- Not sure if your question has been answered on how to unsubscribe from a topic. Click on Tools, click on Manage Subscriptions, a page with all your subscriptions pops up, find the title of the thread you no longer want to receive, along the right side of the page you see unsubscribe, click on that, a box pops up "Do You Really Want To Unsubscribe?" click Yes.

I'm having a problem right now. I'm not receiving my subscribed threads in my e-mail for the past 48/72 hours.

Thanks Mark. It just makes it a pain to remember the threads you have been on and go back and check for feedback and responses.
