Ian,
in my very non techy way I will try and help!!
In the top right hand corner of your screen it says "Welcome, IanBond" Directly under that is a hyper link that says "Private Messages". Click on this. When you get to the next screen you need to click on the section on the left of the screen that says "send new Message". Then a box will come up saying recipient (type FloridaLol in here - you need to spell it correctly and have the right spaces there for it to work). Then type your message in the box below, then click on send at the bottom. That's it!
Hope that hasn't confused further, it looked simple when I started to write it!!
