You can message other members publically through the forum, but if you want to message someone privately all you have to do is go to "MEMBERS" and click on the message button below the member's name. (Another way to message privately is to open the "Members Chat", click new chat, and type in the name of the member you want to privately message.)
NOTE: If you type a message in the "Let's Chat!" section in "Members Chat" it will just go directly to me. You can send any questions or concerns to me using this feature.
