I must admit that I have made some unintentional mistakes in the past. Most though,
haven't been in role-playing. In fact most of my blunders have either been in this forum, or in Newcomers. I'm thankful that most of them have been on deleted threads.
I wonder though if Tolkien (being a professor) were alive to day, would he be insulted by all the gramatical mistakes some fans (like me) make frequently?
