No DB Needed Guestbook

This is a simple ASP guestbook script that does not use database. The file reads the guestbook data into a value then overwrites the data file inserting the most recent entry in the file, then it writes the previously read data to the file. This is done so the most recent entry is at the top of the guest entries. The only thing to remember is if your data file gets too big it could slow things down, you'll want to delete the entries every so often to keep it fast.
