--- Comment #6 from Dennis Clarke <dclarke@blastwave.org> ---

I have no idea how to create anything in the mystery site that is=20
running phabricator.  This thing --> https://reviews.freebsd.org/ .

Therefore I have a real barrier to entry to do anything there.

So there is no issue with a pool name that begins with "c[0-9".
