Ok finally got PVNC to work. It is probably the most amazing thing that I have seen. Thanks to all the guys that worked on it and wrote the tutorials...I would have no clue how to do any of this stuff without it.
For my question I would just like to know how safe it is to use VNC. I know that you have to have a password to connect but is there anything else I should watch out for while using it, or anything else I can do to help protect my computer to keep other people from using it.
