Yes, I hate when websites prevent me from using the "+" in my e-mail
address, claiming it's an "invalid" address.  I had previously read RFC821
(yes, I'm a geek) to see about this, and I mis-read the specs and thought
that "+" was not allowed, so I let it go.  However, after your post, I
reread it, and it turns out that RFC821 specifically allows:

     any one of the 128 ASCII characters, but not any
     <special> or <SP>

where "<SP>" is the space character, and "<special>" are the control
characters and a small list of "forbidden" characters:

     "<" | ">" | "(" | ")" | "[" | "]" | "\" | "."
               | "," | ";" | ":" | "@"  """ | the control
               characters (ASCII codes 0 through 31 inclusive and
               127)

Note, however, that it also allows "quoted-strings", which allow *any*
characters inside quotes, so technically, this is valid:

     "Smith,Bob^T(SETI at home)^T(212)555-1234"@example.com

Hi JP:

     Here is the last email from the last email thread that I could find.
There were other email address edit posts, dating back to at least 2005, if
this doesn't work for you.

Cheers!
