I joined as "simbaflyingoveracliff" which is a gif i had as my avatar because it cracked me up so hard. (apparently before my time there was another poster named simba or something like that, but that's not me)
However i have more commonly been known on the autism forums as lang or conlang. i've also had dozens of other names but I have long since forgotten most of them.
Gonna change my name to something like return of conlang so people can recognize me, but currently it's "gotbored with lions"
