*Bug hunting.* A port may be affected by bugs which are specific to FreeBSD. You will need to investigate, find, and fix these bugs when they are reported. Thoroughly testing a port to identify problems before they make their way into the Ports Collection is even better.
*Changes affecting dependent ports.* If other ports depend on a port that you maintain, changes to your port may require coordination with other maintainers.
*Changes to dependencies.* If significant changes are made to the dependencies of your port, it may need to be updated so that it will continue to work correctly.
*Changes to ports infrastructure and policy.* Occasionally the systems that are used to build ports and packages are updated or a new recommendation affecting the infrastructure is made. You should be aware of these changes in case your ports are affected and require updating.
*Changes to the base system.* FreeBSD is under constant development. Changes to software, libraries, the kernel or even policy changes can cause flow-on change requirements to ports.
*Interaction with other users, maintainers and developers.* Part of being a maintainer is taking on a support role. You are not expected to provide general support (but we welcome it if you choose to do so). What you should provide is a point of coordination for FreeBSD-specific issues regarding your ports.
*New software versions and updates.* New versions and updates of existing ported software become available all the time, and these need to be incorporated into the Ports Collection in order to provide up-to-date software.
A detailed description of their actions, expected program behavior and actual behavior
A large and growing number of international contributors, of greatly varying ages and areas of technical expertise, develop FreeBSD. There is always more work to be done than there are people available to do it, and more help is always appreciated.

Adopting an unmaintained port
After filing a report, you should receive confirmation along with a tracking number. Keep this tracking number so that you can update us with details about the problem.
An addition or change to the existing source code is a somewhat trickier affair and depends a lot on how far out of date you are with the current state of FreeBSD development. There is a special on-going release of FreeBSD known as "FreeBSD-CURRENT" which is made available in a variety of ways for the convenience of developers working actively on the system. See link:{handbook}#current-stable[The FreeBSD Handbook] for more information about getting and using FreeBSD-CURRENT.
An idea or suggestion of _general_ technical interest should be mailed to the {freebsd-hackers}. Likewise, people with an interest in such things (and a tolerance for a _high_ volume of mail!) may subscribe to the {freebsd-hackers}. See link:{handbook}#eresources-mail[The FreeBSD Handbook] for more information about this and other mailing lists.
And Finally
Anyone can get involved, and there are lots of different ways to do so. Contributing to ports is an excellent way to help "give back" something to the project. Whether you are looking for an ongoing role, or a fun challenge for a rainy day, we would love to have your help!
