Anyone knows anything about youtube here? This fucking google+ shit drives me nuts.

[Objective]

I want to change my youtube username, but I can't seem to be able to change my youtube URL which is stupid as fuck. Is it because I made this account before all the changes? The entire Channel Settings column along with the ''Create custom URL'' option isn't there as shown @ 01:34 here: Does anyone know why?

I also managed to add an extra account so when I click ''choose account'' there's a duplicate there that I don't want. I deleted it, from both google+ and youtube, but it still shows up when I click ''choose account''. It annoys the fuck out of me.

Fucking hell Google. You had to fuck it up, didn't you? Everything was fine and dandy until you came along, you even managed to royally fuck up the comment section on youtube.
