I accidentally ignored a thread. How do I un-ignore it?

[Emo Furcorn]

The thread was "What are you listening to right now?"

I accidentally ignored it and now I can't get in it.

If you go here you can see all the content you've ignored and choose to unignore anything.

Additionally, on the bottom of boards with ignored content (below pagination), there is a link to show that content until you reload the page.
