This question is an exact duplicate of:
- Preview of a proposed edit? 1 answer
Sometimes I see that there is an edit waiting to be reviewed, and I would like to help out, but I'm not really confident in my MathJax (with good reason) and the few times I've tried to review an edit, I've given up because I can't really tell what the MathJax says.
If there were a preview panel, I would be glad to do my share.
