I’ve always felt like one of the younger people here, but based on the responses to this thread I’m clearly not the youngest. In fact I’m in the largest group of poll respondents (I’m 46).
Probably Curtis Lemay. That was quite awhile ago though, so he’s probably not still young.
Yep! Thank you. 
I have the wisdom and maturity of a fifteen-year-old boy. But my driver’s license and knees tell me I am in my 60s. That just doesn’t seem right.
Sounds like you need a fake license and new knees
I’m 38. I know there are a few Dopers here who are, I think, also in the age 36-39 range. I’m not sure who else here is a frequent poster who’d be younger than 36.
I joined the Dope at age 26. Man, times flies.
I’m 64 yet according to the poll results I’m not in the oldest 25%.
Originally Qin Shi Huang. (Or vice versa?)
As I recall his original user name was of some of some ancient Chinese emperor. Then changed to Curtis Lemay who was a US Air Force general. I tried to search but all I get is Star Wars characters. A bit conservative so I doubt he is still here.
Are you thinking of @melaniethewitch ? She posted about some goings on at her high school (rather vaguely, I might add, and a mod had to coach her about being clearer), and she’s posted in a few threads since then. I don’t know if she’s still active?
Yep, that’s her!
Hope she’s doing well.
I’ve jumped two levels since joining. I’ll be 79 in six days.
I often wonder, especially when someone posts a video filmed in black-and-white, if some Dopers’ children know they’re using the Internet, and whether that’s OK with them.
There was the weirdo kid who was really into dead languages. They said they were 13, I believe.
I searched for his old name (Curtis) and it brought me to his new one. @Qin_Shi_Huangdi. Oddly enough, today is the seventh anniversary of his last time on the SDMB.
There is/was another recent teen-ish woman who’s not melanie. IIRC name started with L, but with 133K users, that’s very roughly 5000 per initial letter, so not to practical to page through. Search is not coming up with what little I remember about her teen laments.
What is the lower age limit here? I thought there was a poster here a few months ago who was 13 or so–and the mods threw him out.
I’ll also point out that the poll is flawed by overlapping boundaries. Anyone of age 35, 45, 55, or 65 has two different age groups they can select, one which starts with that age or one that ends with that age.
AFAIK it’s 13 according to the Terms of Service. Or was, when I signed up (I was well past being old enough at the time). If a teen got thrown out it was probably due to rules violations (posting nonsense, would be my guess) or failing to follow mod instructions or what have you, not necessarily his age.
There was Shockaholics, who posted here but had an inconsistent story:
