Documentation links on the forum are oftern broken

Seems a change at some point broke a LOT of the very helpful links in the forum e.g. at the end of this thread - Add instagram link to the navigation - #6 by kmutahar it links out to which is a 404.

The correct link is How to add social media icons to your Ghost theme

Not sure if a search/replace is possible, or a redirect on the webserver - but i expect you are getting a LOT of confused users as a result.
