1- Append a plus ("+") sign and any combination of words or numbers after your email address. For example, if your name was email@example.com, you could send mail to firstname.lastname@example.org or email@example.com. The email will receive to firstname.lastname@example.org.
2- Insert one or several dots (".") anywhere in your email address. Gmail doesn't recognize periods as characters in addresses -- we just ignore them. For example, you could tell people your address was email@example.com, firstname.lastname@example.org or email@example.com. (We understand that there has been some confusion about this in the past, but to settle it once and for all, you can indeed receive mail at all the variations with dots.)
