I'm a little upset. I was just writing my first answer for Stack Overflow. It costs me a little bit more than half an hour writing it. After pressing 'Post Your Answer' and answering the 'I am a Human being' question I thought I completed the task. A few minutes later, I wanted to add another line and saw on the page that there was still the editor only with half the content I wrote.
So my question is: Why did it happen and what can be done to avoid such trouble in the future?
Edit: Fast forward, for those wondering: after getting my closed tab back and clicking a few times back, I found my original post again. After posting the answer again I found the problem. I had five links in the 'How to write great answer' with the advice to support the answers with backlinks...), but for a new user only two hyperlinks are allowed.
