Not sure if this is the correct forum to post in or even if I have a problem but since upgrading
I have received a number of unusual  emails from the coppermine contact form
this is an example
This email was sent at 2012-02-09 17:02:23 using the contact form at http://www.mareham-le-fen.co.uk/photo/contact.php

Can I just ignore it or is something to worry about
