ok i know you applaud some one but how???
Right above their avatar on each post, there’s the applaud and boo buttons. You can only click one per day or something though I think.
ok…still dont see it…i think myblonde streaks are getting to me!
only if you have 100 posts.
You need to have 100 posts before you get the applaud/boo POWER!! 
. (I think)
It’s 100, and You can only applaud someone again after 48 hours.
