# Editing an old post to add MathJax

Sometimes I come across an old post which does not use MathJax. Is it OK to edit such a post if the edit improves readability?

This question (and its answers) motivated this post. I know some users aren't fond of bumping old questions, so I thought I'd check.

• I think it's fine to do so. – Todd Trimble Nov 3 '16 at 22:52
• Limit yourself to reviving at most 5 dormant posts per day. – Gerald Edgar Nov 4 '16 at 12:53
• Rather similar older discussion: What's our consensus on people resurrecting old questions just to edit formatting?. BTW I think that (bumping) would be an appropriate tag for both of them (but I don't have enough reputation to edit on meta). I am not sure whether it adds anything relevant, but I will also add link to this conversation in chat. – Martin Sleziak Nov 4 '16 at 15:28
• @GeraldEdgar: Sure. I wasn't planning to go looking for posts. – Michael Albanese Nov 5 '16 at 0:29

• It depends whether the LaTeX is warranted. Editing to put  around a variable is not really that important. But posts where the user used no LaTeX formatting and extensive pseudo-TeX clearly can benefit in terms of readability with the edit. – David Roberts Nov 6 '16 at 13:40
