+### People
+The GAP Group consists of many different people and
+is most interested in close contact to the users of GAP.
+On one hand we hope for feedback from users, on the other hand we are
+offering to give support to users as well as we can. However with both,
+reacting to feedback and giving support, users are kindly asked to
+understand that all this is done by colleagues who provide such service
+in addition to the work for their regular job.
+
+### Feedback
+
+We hope for feedback in particular in the following instances.
+
+-   **When using GAP.**  If you have used GAP we would appreciate some
+    information about your work via an email to the address
+    <[email protected]>.
+
+-   **When publishing results.**  When you publish results
+    obtained in part by using GAP we ask that you quote GAP (see
+    recommended [citation]({{ site.baseurl }}/Cite/cite.html)) and
+    tell us about your publication again by email to
+    <[email protected]> since we would like to include a reference
+    to your publication into the
+    [Bibliography]({{ site.baseurl }}/Doc/Bib/bib.html)
+    about use of GAP.
+
+-   **When encountering bugs.**  We strongly appreciate timely reports
+    about any bugs in GAP you may encounter. When reporting a bug,
+    please follow [these guidelines]({{ site.baseurl }}/issues/).
+    The preferred way to submit bug reports is to use the [GAP issue
+    tracker](https://github.com/gap-system/gap/issues) on GitHub.
+    Alternatively, you may send them to <[email protected]>.
+
+### User Support
+
+We offer to react as well as we can to questions, requests for help with
+problems, or complaints that you may have. However, for the sake of the
+whole user community of GAP, we ask you to separate these into two
+different categories.
+
+-   **GAP Support.**  We would like to deal with those topics that are
+    more or less local to you, that is, are likely not of interest to
+    most of the other GAP users by direct correspondence with you.
+    Please send letters about such **local** problems and questions also
+    to the address <[email protected]>.
+
+-   **GAP Forum.**  On the other hand, the
+    [GAP Forum]({{ site.baseurl }}/Contacts/Forum/forum.html)
+    should be reserved for discussions about problems that are likely to
+    interest many of the GAP users. It would also be welcome if you
+    could occasionally tell other users in the GAP Forum about
+    interesting applications you have made of GAP. All correspondence in
+    the Forum is kept in the
+    [Forum Archive]({{ site.baseurl }}/Contacts/Forum/forumarchive.html).
+
+    For **theoretical** questions on groups and related structures we
+    like to point to the
+    [Group-Pub-forum](https://people.bath.ac.uk/masgcs/gpf.html) in
+    which such questions are answered and discussed by a large community
+    of experts.
+
+### Cooperation
+
+The functionality of GAP has been widely enlarged by pieces of code and
+data collections that have been developed by users of GAP and have been
+provided to be used with the main GAP library. We distribute these in
+the form of
+[Packages]({{ site.baseurl }}/Packages/packages.html) and
+Data Libraries.
+We welcome obtaining any further such contributions as well as
+references to GAP implementations in the course of your research
+projects.
+
+As explained on the respective page we have established a procedure for
+formally 'accepting' some packages which we hope will give them a
+status comparable to a published paper. On a separate page we inform
+about the process of [submitting contributions]({{ site.baseurl }}/Packages/Authors/submit.html).
