Hi John,
To join the Linux forum, just click on the folder in the top righthand croner of your screen to access your account. Then under [Update your account], select forum. Put a check mark in the box adjacent to Linux.
You can access the swat GUI to smaba by click on the start menu. Then click on the extras stuff. Once you have joined the linux forum, post any question there about samba and you should get plenty of help.
