With me being really busy lately I'm even more forgetful about the messages I have to reply to on YouTube. And it has been pretty bad before, I can tell you! So sorry to all those still waiting for my answer. The thing is that YouTube has one of the worst messaging systems I've encountered so far and it got even worse lately with my new (involuntary) linking to Google+. I do not get any visible updates for new messages or comments at all anymore on the YouTube standard page, but have to click through three subcategories before seeing whether someone messaged me. Also, there's no option to mark messages as 'unread', so I have to reply at once... or never! It's ridiculous, really.
So please: if you want to ask me anything or want to discuss a game or just feel in the mood to chat, refer to this mail address instead: firstname.lastname@example.org
