That's an amazing reason to name yourself that!
Ummm, just say 'i' anyways and forget the _ and screw the capital letter haha

Did the admins change it? I remember that it used to say i

I typed it in as "I" but apparently only admins can have a caps as far as I know. It was indeed "i" for about two days but my profile URL lead to the FS home page funsubstance.com/i via a redirect from instagram. And now my profile is i_ as is my name.

Ah, that's confusing

You should have use the letter L
I mean capital I is exactly as normal l

But then I won't get the mentions using the @ function

Nothing is perfect isn't it
