Okay, so you may want to help out with the wiki but feel your posts may not be accurate. This is how I felt when I started editing a different wikia, a while ago. If you feel this way, I would just add on the bottom: Edit: [message]
So then, you are not really changing anything, just adding on. Then, as you add more and more, your confidence should grow and you can start editing out purpose mistakes, add pages and etc..
