The continued improvement of libSBML is crucially dependent on your feedback. Below are some means of discussing and sharing your experiences.

## Reporting bugs and other problems

Please report problems and other issues using the issue tracker for libSBML on SourceForge: http://sbml.org/Software/libSBML/issue-tracker.

You can also report problems on the sbml-interoperability mailing list (see next section). This may have advantages, such as that other people may also have experienced the same issue and offer a workaround more quickly than the libSBML developers can respond.

Finally, if you want to contact the libSBML developers directly, you can email them at libsbml-team@googlegroups.com.

## Mailing lists, web forums, and list archives

If you use SBML (which seems likely, if you are using libSBML), we urge you to sign up for sbml-announce, the SBML announcements mailing list. It is a low-volume, broadcast-only list where new releases of SBML and other important events are announced. These announcements are not cross-posted to the other lists below, so it's important to subscribe to sbml-announce even if you subscribe to the other lists below.

In addition, if you use libSBML, we highly recommend that you subscribe or monitor the mailing list sbml-interoperability. Subscribing to this list will enable you to keep in touch with the latest developments in libSBML as well as to ask questions and share your experiences with fellow users and developers of libSBML and other SBML software. The mailing list is vigilantly moderated by humans to prevent spam and off-topic postings.

If you are interested in delving more deeply into libSBML, perhaps to make extensions and modifications, we recommend that you also subscribe or monitor the mailing list libsbml-development. Being a member of this list will enable you to keep in touch with the latest developments in libSBML as well as to ask questions and share your experiences with fellow developers and users of libSBML.

Web-based interfaces for all lists are available at http://sbml.org/Forums/, for those who prefer to interact with the list via a web forum interface. This website is also where you will find the mailing list archives. (The lists and the forums are cross-posted, and the archives are identical to each other.)

## Notifications via RSS and Twitter

If you wish to get notifications of mailing list postings via RSS, an individual feed for each mailing list mentioned above is available at http://sbml.org/Forums/.

If you wish to get general announcements about SBML and its use, you may want to follow sbmlnews on Twitter.

## The SVN notification mailing list

If you are obtaining your libSBML files directly from the SVN repository on SourceForge, you may wish to subscribe to the mailing list sbml-svn, to be apprised of changes to the SVN repository as soon as they are committed. You can join the list by visiting the URL https://lists.sourceforge.net/lists/listinfo/sbml-svn.
