Or, in other words, a random letter producer is just as likely to throw out joshSCH as aaaaaaa, BodoNeE, pAFdOJS, KUMQUAT, or any other set of seven randomly-cased letters: 1 chance in (52)^7. It's just that some of those combinations will have valid meanings.

actually, there's more people that know me as "Niche" than people that know me for my real name...
