#1 Do not send email if email address is blank

[John Mazzitelli]

Some people may not have email addresses or may not
have email addresses that we can send to. Before any
and all sending of email, check that the email address
is not empty. If empty, skip sending the email. The
member row in the database should have the email
address column as a blank. /^\s+//g and /\s+$//g should
be used to strip the email address of leading and
trailing spaces prior to the check.
