Topic header editing question

Can I edit a topic header for a topic that the posted header is a link to YouTube? I would like to change this thread to a Microsoft Flight Simulator mega thread. Do I just make a new thread and merge this one in? What is the best practice?

On another note, I’ve got this strange rash near my family jewels, if I post pics can someone diagnose it?

Not sure I understand what you are trying to do. What do you mean by topic header? The title?

You can paste the youtube link as the title and it will pre-populate the info for you. Is that what you mean?

You should be able to edit the topic or post title. You also should be able to edit the first post content.

Usually I have no problem editing the title, for some reason it is not showing the little edit pencil:

What I am trying to do is change the title of the aforementioned thread to “MS Flight Sim 2020 mega thread

done.
