Apart from static layout, each website contains a set of interactive elements that facilitate contact, communication, access to information or some online operations. The system web kameleon is equipped with a wide range of selected mechanisms, that are the most frequently used in internet services.

These mechanisms (built-in services) include the following:

• search engine - enables users to search through the website content for a phrase or character string. Special content indexing makes the engine work very fast.
• discussion forum - permits continuous communication with users and sharing opinions concerning given topics. An indispensable tool to build up a community around the website.
• recommend the page - a simple mechanism enabling users to recommend the website to their friends by sending them its address with a brief comment.
• news - features managing information about the company's news and events. You enter the information only once and it is automatically displayed in all predefined locations.
• guest book - many users eagerly put their entries in guest books. These entries frequently turn out valuable clues for the website editors.
• contact form - enables users to contact the company quickly and directly, with no need to use e-mail applications.
• notice board - users can put an entry on the page: each notice has a predefined expiry date, after which it is automatically deleted.
• site visits counter - in a nice, graphic form presents the number of the visits on the page where it is located. It provides accurate information about the popularity of the website or its particular parts.
• site map - dynamically created on the basis of actual website structure. It lets users quickly find what they are looking for.

Settings of all standard services can additionally be configured directly by the user of the system.

The open architecture of the web kameleon system allows for new features and mechanisms, in this way creating a tool that suits user's needs even better. For projects where the standard capabilities of the system are not enough (API modules), the design, development and implementation of individual mechanisms is an option.
Elements that can be used to extend system features include:

• extended news module - allows for displaying the time (date + time) when information was published on the site, automatic creation of news archives, attaching images both to the news itself and its abstract.
• Banner system - allows for placing and managing ad banners on any page of the website in predetermined formats. The system makes it possible to set a date for the display of the banner (time frame), its displayability, target location, etc. The administrator can monitor the display statistics and clickability of the banner.
• Questionnaires and surveys - this module enables unaided surveying on the web site. The administrator formulates a question and alternative answers for the Internet users to choose from. The system presents answers on a diagram.
• Newsletter - a system which enables automatic and customised mailing of specific user groups. The website developer, after writing a message, sends it with just one mouseclick to recipients selected from a database.
• Online store/second-hand shopping/auction/directory - solutions for online sales which involve mechanisms designed for the management of user databases, displaying and updating of the product range, order execution and supporting logistical solutions.
• Chat - at the client's wish the web kameleon system can be integrated with a proved Polchat solution.
• Statistics - the web kameleon system supports the creation of a website map, which is then subject to a statistical analysis by the Gemius system.

The functionality of mechanisms described above can be tailored to suit the needs of any individual project.
The web kameleon system additionally allows for additional (pre-developed) interactive mechanisms, databases, scripts or forms to be included. Web kameleon can also be integrated with external applications, systems and databases that a company has been using so far.
