On 25 May 2018 I changed my username globally from Richard0612 to Firefly, purely to have a simpler, less convoluted username. Bonus points for anyone who can work out where the inspiration came from, and no, it's not the lampyridae. ;)
For reference, my old sig for my old username looked something like this:
Richard0612 20:24, 24 February 2009 (UTC)
and my new sig looks like this:
ƒirefly ( t · c · who? ) 09:04, 25 May 2018 (UTC)
But the posts were both made by me.
