I just discovered a problem that never existed in my mind before. I have a regular signup script which accepts username, email and password.
I do not allow special characters or upper case in username so a standard search in the mysql database yields the desired result.
However, for email i do allow special character such as " . " I just realized that, in case of gmail when I email to email@example.com or firstname.lastname@example.org or email@example.com the email will be delivered to firstname.lastname@example.org. This means that a person with one gmail id can create multiple account on my site. Which would be bad for me.
Please any one, any suggestion on this please?
