how do you "like" a badge on this new forum?

If you're thinking about the achievement thing, go to your profile and click on one of the circles with a question mark in them.

Far as I can tell it we have the "topic upvote" option high above on regular topic

Apparently not on question topics like this. Wait, scratch that, those Question topics seem to have those too.

However, "Question topics", seem to have an upvote option on "answer comments" which regular topics don't have.

That should take care of the "answer like" for the badge unlock stuff I assume (so yeah, someone willing to hit me up with a like here?). I throw a bone to Monochromatic too ;)
