Php guestbook thing: What is chmod? How do i do it?

"This file will need to be placed in the cgi-bin of your server and chmoded to a+rx"





My html knowledge includes changing font colors, making links, etc., and some things i've copied and pasted. I downloaded this Guesbook thing from http://www.scriptarchive.com/guestbook.h... and would someone please take a little time to explain to me how to chmod the file?





(Well, I don't really care what it is and if i really want the definition i'll search for it on wikipedia or something... i just want to make the guestbook work. thanks)

if you're using Windows, you don't have to sorry about chmod. Just right-click on the file, and make sure that it isn't marked "read only." It probably isn't. You'll probably be just fine if you just put the file in the right place and go. :-)
