There is a contact form under the 'Contact Us' item on the left menu. This presents a form that can be sent to one of two 'Categories'. The 'Poetry Aloud' option will send the e-mail to Rob Lock, the 'Website' option will send it to Colin Whyles, the webmaster.
If you wish to submit poems, it is easiest to e-mail them directly to Colin on email@example.com. You can attach your poems to your e-mail that way, which you cannot using the contact form.
Please remember that this site is for poems written or read in Suffolk, UK.
