...do you regret signing up with your first username? Yep we're allowed to change it so no biggie. But do you ever regret you signed up with the username you had at the time? It doesn't have to be on ZD but it can be on any site.
The "tm" reminds me of when I started playing Shadowrun and named my character ©frock. Felt natural to incorporate corporate legalism into my fundamental identity in a cyberpunk game. A friend of mine hated that I did that (probably because it was too awesome for him to handle), so I changed my name to ©frock on Discord, too. He couldn't tag me any more since he'd type "c" and nothing would come up. His suffering was delicious.It’s my brand(tm).
