It’s going all a bit off topic, but linking to an individual post works ok
Just copy the URL of the top right hand blue post number.
As I recall, you need to then insert it As An Embedded Link like this which should then open the overall topic with this post at the head of the relevant page.
Just inserting the link like this may not give the same result; screenshot below so it doesn’t auto-resolve
That link is inserted directly below to allow the site to resolve it.
Finding a post by number, How?
Where I struggle, is how to search the forum for a post number, unless you know the topic title.
In which case, just open any post in that topic and edit the last number in the URL.
Yes I know it’s messy
