Apparently, using it for decoration purposes is always wrong (actually, it was for demonstration purposes, but whatever), even outside of signatures. Well, I'll just have to play around with it in PMs then.
Yes, but your new name surely isn't that much different.
As for the last part of the message, name changes came back. Kinda funny the last time you interacted was in 2012, but man I am very different now compared to then, since I'm a supporter now and got rid of that terrible name I once had.
