Yes, and maybe a few more characters too, based on what we see in common usage
(e.g at and  But keep it to
a minimum, so that we have the flexibility to do new email routing later and
still have several reserved chars at our disposal for separators.

Another change could be to allow a non-alpha as a first character.   That was
mentioned on but is more relevant
to implement here on  That said,
I don't know what the use-case is.  If it's not for code repos then it's a
different story altogether.
