As admin, can I change the poster of a single topic to someone else?

[Mareid]

I am the admin of our forum.  I posted an ad for a user at her request, but I'd like to change that post from me to her.  Everything I've read says I can change all posts in the database from "admin" to someone else but I only want to change a single post.  Is this simply impossible or is there a way to do it.  I'm using 2.13 on Windows 11

no.

You can attribute *ALL* posts by one user to another... but not a single post.

To do that, you would need to make changes directly in the database (NOT recommended)

there ARE mods that allow you to post as another user - but switching a post AFTER it is made is more difficult.

I would suggest you, the solution of a mod, which I use.
(If I understood your request correctly and of course the decision is yours, always)
You should install the mod https://custom.simplemachines.org/index.php?mod=2626
and then go edit the article, where under the title, you have the option to change your username.

I have the 2.0 version of that mod on one of my forums, it will do what you want but is a bit difficult to use.
