It's pretty easy. You can see there are lots of Text options and of course emoticons . On other people's posts on the bottom right is the reply button and a list of ratings you can give someone's post if you like or dislike it. The front page is where I stay most of the time and next to the forum type is the latest posts so you can jump in on the action. General discussions is the main forum where people can discuss things. If you have a more specified post there are other categories as well. And every member has a profile where you can post things and see their activity.
