PowerFolder offers the possibility to contact other Members of a Folder or Friends. To do so just right-click on a user, or a friend and select Chat. You will be able to write some message and send it by hitting "enter". The user you wrote the message to will receive a small pop-up, which offers him to answer, or to ignore your message. To send a message to some Folder just right-click on the Folder and select Chat. You will be able to write a message but there will be no pop-up on a Folder message.
