Here's how to chat with the e-nauts.
To manage your visibility, just click on your name in the upper right of any page of e-nautia.
To communicate instantaneously with a member, click on the icon from their page or a member list. You can then start the conversation. If the e-naut is online, he will immediately receive your messages. Otherwise, they will receive them the next time they log in.
You can receive a conversation from any page of the site. Once a member tries to contact you, their messages are displayed immediately if you are online. If you go to another page or click on the cross to close the conversation box, the conversation will smoothly resume upon receipt of a new message. This way, you can navigate without worries.
