I do have tho - a working guestbook (which I found at Matt Wrights website)
Do be very, very careful with that. There has been plenty of discussion about that collection of scripts over the years and almost all of the recent comments have been uncomplimentary. The scripts are very old and at least some are very insecure. See the summary at the NMS project for some background and how to obtain better versions of those scripts.
The monks here can help you with your perl questions but if you are going to try to patch some of Matt's old code often the better strategy would be to start again from scratch with the benefit of a modern approach and security as a primary principle.
Addendum: For the benefit of non-English speakers, there is a word in English which means "appending to the beginning" and it is prepending. Appending is reserved for adding to the end only.
