As much as Dave (seven006) hates it, you might want to try using smilies to indicate when you are being humorous. It is kind of hard to get used to the idea that we can't see your wry grin and twinkling eyes. You have to actually communicate that part directly, too.
Don't cry. Don't toughen up either. Make horrible (dreadful, unforgiveable, terrible ) mistakes, get widespread shoulder jostling, apologize, get widespread think nothing of it's, and move on. You don't have to be overly tough or overly tender, just be you.
Most importantly, remember: You will never make everyone like you, no matter who or what you are. But if you are at least 95% your genuine self, even those who don 't like you will respect you. (<--- please don't take that to mean I don't like you...lol)
All we can see is what you type, we can't see what you mean by it. It is a medium that allows for great range in communication (you are from New Zealand, I am from Albany, Georgia USA) but comprehension takes a hit because most of communication is in body language. So, if you don't explain it, odds are someone will misunderstand it.
