Feeling happy? Sad? Annoyed? Need to get something off your chest?
If it's something small that you just want to share, no need for a discussion, no need for (many) further replies, go ahead and post it here.
Three sentences or less though. If you can't summarize it in three sentences or less, you probably want to create a topic instead. At that point, there's probably something worth talking about in a proper topic. Don't worry - we have more than enough space left for the forums that it won't get in the way.
If you want to reply with more than a few words, that's also the point to make a topic about it. We can split posts off this topic if we have to.
