Easy textfile news system w/out categories.
This script is an easy way to have a text based news system.

It is very simple to customize and will build the folder structure itself. All you have to upload to your webspace is this one file after providing a password for the "add news" form.

Simple, straight forward, easy to use.

Hope you like it!

Chris

Easy textfile news system
This script is an easy way to have a text based news system.

To add news, call index.php?add=true in your browser. Please provide a password
in the function showaddform().

The system will generate a folder structure like the folloing

Year Month Day Newsfile
------------------------------------------
2007 -
|- 01 -|
|- 30 -|
|-timestamp.news
|-timestamp.news
|-timestamp.news
|- 31
|- 02
|- 1
|- 2
|- 03
|- etc

In the newsfile, the first line is the title, second is the header text and third and following are regular text lines
