Topic Notifications

Would it be possible to be able to subscribe and unsubscribe from a thread without having to post anything. I tried this and the forums will not let you checkbox and just submit without writing some text.

Sometimes there are threads that you are interested in following but you might not have anything specific to add to the topic.

For example if there was a plugin you’re not using yet but was planning to use; and someone posts ‘How do you do something with it’. You might want to see how that goes but as you’ve not used it yet may have nothing interesting to add to the whole discussion.
