Simple one-file guestbook

This is a simple one-file guestbook. It uses a flat textfile to store all entrys and then the .php file with the whole script inside. Very easy to embed into any homepage. It has admin login where you can remove entrys. It has protection against html and other scripts being executed in the guestbook. More info in the readme.txt. >> Version 1.2 released: A major update has been released with big updates. * The admin section is now not only a html textarea, it is changed to a list of the entrys where you can select them one and one and delete them. * The whole code is slimmed down and cleaned up a bit. * The way the posts are stored is changed so the file does not contain multiple long rows of html. There is no backwards compatibility for earlier versions because of the big updates. >> Version 1.3 released: After version 1.2 the guestbook only worked on PHP5 and with this update I fixed so it works on both PHP4 and PHP5. I would also like to thank Major_Meatbone and tcp for helping me.
