I've recently joined the Game Development community and noticed, that there is one recent display name available in my profile:
I never had such a display name on that site.
BTW, the number in the username, 2147482262, is 1386 less than 2^31 (max value for 32-bit signed int plus 1).
If the "-" counts, then -2147482262 is 2147485034 as an unsigned 32-bit number, 0x8000056A.
