...lol thanks Kumquat. This is why you're so heroic.

The only problem is that I don't actually know how to like stuff... :/

On your phone, there's a little star if you open up the options on a post. I think you do that by tapping the bottom of the screen. On a comp, it's just the up arrow. There's a number on the left side, at the top of each post? An up arrow over it, a down arrow under it. Clicking the up is the like.
