From one of our (Wireless Toronto) users:
I just tried to create an account at https://auth.wirelesstoronto.ca/,
but your sign-up form handler incorrectly determined my email address to
be invalid.
I suspect that you're using a too-restrictive formula for determining
valid characters; I've seen this before, where sites block use od the
plus character ("+").
Can you fix this please? I'd like to sign up, and possibly get involved
in other ways.
