Paul you will need to move your models to the spray booth soon, and kick the cossie out, you got that many!!
as for putting links up a quick tutorial for ya.
whilst on the page you want to link to left clic in the address bar at the top of the screen, this will turn blue.
press "control and C" at the same time this will copy the address.
go to PF and it the text you are writing press "control and V" this will paste the address into the text, job done!!
regards,
steve
