Cutenews
Cutenews is a simple to use and easy to configure blogging/commenting system.
Firstly you must have a domain or subdomain. You don't need your whole site to be PHP you can still use iframes and use cutenews.
Go to CutePHP to download cutenews. After that's done extract the folder to your desktop then upload it to your ftp programme. This may take a while....
Then go to the cutenews folder, you should see a data folder, right click it, choose the Attribute/CHMOD option, and changes its permissions to 777 then click OK.
Now you have to go to your cutenews homepage, this should be something like
http://yoursite.com/cutenews/index.php
Obviously change the 'yoursite.com' to your domain name. Now
you will be on the cutenews installer page, click 'Proceed Installation' and it will start to install, it may ask you to delete a file for security reasons, delete it. Fill in your details, this is your cutenews login information. Afterwards go to Options > Interation Wizards > Integrate News, there will be a form, just type the number of active news you wish to display on your site (I chose 4) there's nothing else that needs filling in, so carry on.
You should now receive a code, copy and paste this code to your blog page. This maybe on your index.php page or if your using i-frames copy the code into your blog file which should be called blog.php. Make sure the file ends with .php or else your cutenews won't work. Then just upload the page with the code.
To select what sort of stuff you want to be showed in your blogs or comments. Go to your cutenews website and go to Option then Edit Templates. Change each part, for instance, click on Active News, replace the current coding of it to this.
<h1>{title}[com-link]{comments-num} comments[/com-link]</h1>
The example I have given makes your cutenews follow your headers, so the header 1 will be the title of your cutenews and the commenting link. In between the paragraph tags is the actual blog text.
<p>{short-story}</p>
Follow the basic outline I just showed and change each part such as you can use the {date} selection and put it in a header to display the date of a comment posted.
