One of the requests I got was to write a tutorial on how NOT to write a Mary Sue.
All my writing tutorials are listed on this journal entry [here]
along with pending tutorials.
EDIT: A few people have mentioned how this tutorial seems lacking compared to my others. I did not feel there was much that needed to be said in this, after all the basic premise is Mary Sue characters are perfect, perfect is boring, don't do it!
This tutorial is a simple guide to ways I feel you could help to keep you from writing a Mary Sue - after all, many people don't realise they've created such a character.
I also have another Character tutorial
here that covers other notes about writing characters.
As always ALL my tutorials are just my personal opinions on ways and methods to write. They are merely guides to help you (if possible) on looking at your writing style/content/characters etc in a different way.
NOTICE TO ALL WRITERS
My writing blog is now up and running, it will be filled with more tutorials, hints, tips, tricks and general writer ramblings as well as features and competitions. Please visit at [link]
