I need a very simple guestbook with a database as a textfile (my server at work just have PHP 4 support). With this:

1 Textbox (name)
1 Textbox (comments)
1 submitbutton.
And of course all message left.

I would be so glad if some guy (or girl) could help me.

Thx in advance.

Ps. You can also give me some link if you know some place where i can download something like this.
