There are a couple of ways of communicating with other members.
COMMENTSYou can either leave a comment against their blog post, photo, video, or forum discussion - the comment box is at the bottom of the page. You can add photos in your comments.

Comments are public and will be seen by everyone.
If you want to 'Follow' a discussion - click the 'Follow - Email me when people comment' link and you will be sent an email when others comment on the same page.
EMAILSIf you want to send a private email to another member, just look for the 'Send Message' link on the page:

You can also find this link by clicking on a members photo which takes you to their Profile Page.
Emails are private - and sent within the Cookery Network email system, so your personal email is never exposed.
If you have been sent an Email it will be in your 'Inbox':

Just click the 'Inbox' link to read your email.
