this is good advice, and i will add the following:
- all of the rules for valid email addresses are extremely complicated. i
believe there was one attempt made at a regular expression for this,
and it is rumoured to be nightmarish.
- however, do NOT take the easy route and simply assume an email address is:
[a-zA-Z0-9-\.]@{basically the same}
I can't tell how many websites refuse to let me use
"email@hidden". Gmail, in particular, makes frequent and
excellent use of the "+" character.
