I saw some of your replies on the board service to apply, did you get distracted there? I don't find even in any local, that emoticons and a little joke in the thread are natural, I just focus on the important points that are discussed, imagine if it's too standard and there is no interaction, I think it's less fun and even looks like an article fight.  My assumption is that the contributors are very good at responding and ranking with their activities already symbolizing professionalism, if the same media and useful for you, try to get used to writing first from what you like, for me quality will be formed by itself with a record of speaking according to a topic and according to the discussion, of course later you will get used to it. If you think so that's your right, but if you want to improve your writing and way of thinking of course you can make better threads or mingle with other people on any board, if your language can be understood and respectful, I'm sure everyone will be very happy to invite you to learn together on this forum.
