Top of the page, near the left side by the original post. I don't know what it looks like if you're on mobile. But that's where it is on the computer. There's an up arrow and a down arrow with a number in between. Right now that number is 153. Click the up arrow to like, and the down arrow to be an asshole.

Ok I just tried to like by pressing the yellow star, it seemed to do something but no up or down arrows and nothing at the top of page after I click your thread

I think you added it to your favorites and not a like. No worries, just bump the hell out of it.
