Comment Script is a script that allows comments to be left on any existing PHP or HTML page. By default, the script shows name, e-mail, homepage, title, and comment fields, though any can be disabled. The "comment" field is mandatory and must be filled out before the form can be submitted. In order to prevent the script from being abused by automatic spam bots, you can enable the CAPTCHA feature. The script then asks your visitors to enter a text they see in the image below the comment form into an input box. It also features an admin area where comments can be edited and deleted and the front-end language set.
Short URL Script allows you to have a URL shortening service under your own domain. The script can create shorter URLs that do not break in email messages. As a site owner, you can use the script for managing downloads, masking URLs, and keeping track of how many times a link has been clicked.
