FileCMS is a content management system designed by my friend Daniel for online collaborations. It does not have a built in forum or chatbox, but it is easy to use.
This tool may help you with your online projects. I have written both the readme and detailed documentation for it.
Read more about it, or try out the demo here…

If you want the new, complete documentation that hasn’t been added to the package yet, you can get that here… (click save as)

Both the readme and the pdf assume you have cPanel or something similar.
