While using the three-level membership model, One And Only provides some of the best free services, even for Guests (i.e. people who haven't placed a free ad yet.)

As a Guest, you have full access to all members' ads - you can browse, search and view all of them. You can see all details posted by the members in their ads, including their large photos. The only thing you can't do as a Guest is contacting other members. To do that you'll have to become a member yourself.

By placing your free ad you'll get a Free Member status and will be able to receive emails sent to you by other members who want to contact you. Placing your ad is pretty easy. You'll enter some details about you, the most important of which is your description of yourself. There are tips and samples available on the website to help you create a good ad.

Tip: Don't make your description too short - there is a minimum length requirement. If the description is too short, the submission will not proceed further until you update the description to be of an acceptable length.

Your ad will not become avaialble immediately. It takes 48 to 72 hours for it to be reviewed and activated. Once it's active, you'll be able to receive emails from other members.

Paid members in One And Only are called "AYCE (All You Can Email) club members". As a paid member, you'll be able to initiate contact with any other member and send unlimited number of emails to them.
