You need to be already logged in with your whateveritis account to be able to follow the link, otherwise it errors.

I have no idea which is my Twitch account and which is the other account. But hopefully I don't need to figure that out, and it will automagically work.

Does this mean I will no longer be User-123456789 on half my posts?
