I have recently (and finally!) been able to save takes of replays as movies. I'd like to upload them to my YouTube channel, but I'd also like to track them in Team Fortress 2, especially for the Replay Achievements, as well as be able to have them on my "main" account.
The first time I tried to uploaded a movie, I accidentally logged in to the YouTube account that is directly linked to my Gmail. The one I would like to upload to is a Google+ page which is managed by my Gmail account, does not use my name, and already has a video uploaded (my "main" account).
My question is, how can I change the account that TF2 uploads movies to?
