Thanks for the support, the thread crashed once a few years back and it was destroyed. Fortunately it was backed up on the server and was rebuilt but the back up was a little out of date and I had to spend some time on it. It never got back to what it was though.
I am having trouble updating it now and it has fallen behind the times with some obsolete information and dead sites in it. It has been accessed some 190,000 times since it was created, if it crashes again I will not bother to rebuild it as it involves a lot of time.
Thanks again for your support.
