Hey I would like to change my account's username from "iM3nter" to "Fragmenter". Is this possible somehow? Many thanks!

Hello, I'm Fragmeter/Menter, a speedrunner of long games + Mirror's Edge. I've played OMD in the past for over 100h and I am coming back to this game. I'd love to know if the only moderator of this game has discord, and if so, what the tag is. I also would appreciate to know if livesplit is needed for this game, as well as how to manage to get the game running on background. Many thanks!

do i? Or can i just edit the video so the duration of it is the time that started and finished the game run?
