During the past decade open source software has gained increased popularity. A huge number of projects have been developed, published and widely used. Nevertheless, the idea that open source software is created and maintained by a loosely connected community working across the Internet remains suspicious. What is often overlooked however is that communities need support of different kinds. For instance, communities need basic environment to support project sources and documentation, as well as to monitor and to manage contributions, and to communicate with other members. In order to achieve this, community leaders (or supporting companies) often produce a website which contains information about the project. The website may also include facilities for issue tracking, managing communication between members (e.g. mailing lists, IRC, forums, chats, etc.), and access to source code.
