Change forum to GitHub Discussions?

Ok, I'm starting to look properly at migrating the forum now and I have a proof of concept. I can't create posts in someone else's name, so I'm just going to make each new post come from a single Espruino GitHub user, and then put in:

Originally posted at ... by @username

<<post contents>>

(or just username not @username if I don't know your GitHub username)

If you'd like to have your posts link to your GitHub username, please can you post below with your GitHub user, and then I can map the two together when importing? Realistically I won't be able to alter the posts after the initial import.
