Just for info, a 'permalink' is a link to anything - a webpage, an article, a thread, or in this case a post, which is 'permanent' i.e. it shouldn't change in future and is therefore 'safe' to post in a forum. The word was coined when websites - particularly news sites - used to archive articles under different URLs to when they first appeared. I haven't seen that recently but I still see 'permalink' as a tooltip to the button that copies a link to a forum post - often the button is a a chain icon.

Permalinks should not contain extraneous data - from the search you used to get there for example - which you might get if you just copy the URL in the address bar. (Browser often have an option to 'clean' a link when copying it.)

If you look at this thread on concertina.net, and my post, and click/tap the 3-dots on the right, there is a 'share' option which - depending on the device/browser you're using - should allow you to copy the link to that post to the clipboard. That what I mean by a permalink.
