Everyday, many questions are posted on this site(Physics SE) which need to be edited because of many different reasons (like MathJax, grammar, typos, tags etc.). Now, I am okay with the grammar, typos, tags, etc. kind of edits, but many posts contain equations written with bare text. Mostly these posts are by new users, and so we expect them not to know how to use MathJax. And thus with good faith, we edit their posts(at least I do). But, many people take it for granted and thus always expect someone else to "MathJaxify" their post, and don't learn how to use MathJax.
Now in the cases, where there are many equations to be "MathJaxified", I usually drop a comment with a link to the MathJax tutorial, expecting them to learn MathJax and edit their post themselves as soon as possible. But when there is not too much(by not too much, I don't mean trivial, but something substantial which won't take me more than 5 minutes to edit) "MathJaxification" to be done, I usually edit the posts myself. Now, should I do that? Should I let them edit their posts by dropping by a link to the tutorial or should I edit the posts myself? Because I think that people should learn using MathJax if they want to continue posting questions and answers.
