I don't think there is a way to check if a subheading has a link to it from within the wiki, and there is definitely no way to check if there's a link to it from outside the wiki except by searching likely websites to find all links and then examining each one. But Janetmango, don't revert the subheading change that you made.

I'm coming to the opinion that we should make sure that subheadings are capitalised correctly, even at the risk of breaking existing links. To most wiki editors it will seem like the correct thing to do, so editors will keep on fixing incorrect capitalisation in headings. If we ensure that headings are correct when they are created or soon afterwards, it will minimise any possible link breakage. Also, correct capitalisation does definitely look nicer and more consistent!

When I have time, I can check for links to subheadings from the habitrpg.com site, the Data Display Tool, and GitHub. Trello will just have to miss out - it's impossible to search it to that degree as far as I can tell.
