License and terms of use:

• The free version is LINKWARE. This means that if you use this version we require a link back to this page from the page where the messages are posted. This is all we ask in return for the software: a link back to this page. Beyond this, as in the enhanced version, you are most welcome to modify the php code and appearance of the guestbook to suit your specific needs. The code or derivatives cannot be redistributed without our explicit permission.
   
• The enhanced version and the WCS do not require you to link back from your static pages. You are free to modify the code and use it to install a guestbook or comments system for yourself or your clients if you are a webmaster. You can charge your clients for installation and/or customization of the software for a particular install. Conversely, reselling or otherwise redistributing the code as a script package is strictly forbidden by our licence terms and will be actively investigated and prosecuted by legal means
   
• When you download software from this web site, we grant you a licence to use the software. The copyright of the distributed scripts remains, in all cases, property of cellbiol.com
   
• You cannot edit the "powered by"/copyright/credit lines in the scripts source code and the display of copyright notices in the admin section and service pages generated by the scripts
   
• Although we strive to produce and distribute the best possible guestbook/comments software, the use of the software is entirely at your own risk
