Our goal is to make every effort going on as transparent and open as possible. Our official communication channel is the hep-sf-forum.
See the dedicated page about HSF discussions forums for information about how to register and the other existing discussion forums.
There are plenty of opportunities for you to contribute to the HSF, be it by participation in technical discussions, by joining one of our working groups, or by joining the HSF with your software project:
See the Events listing on this site for information on HSF meetings, workshops, etc. Meetings use the CERN Indico system for agenda pages. The agenda pages are open to the world, and no CERN account needed. The Vidyo video conferencing system is used for all HSF meetings and anyone can participate in the meetings from any internet-connected location. Connection information for each specific Vidyo meeting is on the corresponding Indico meeting agenda page. Vidyo has a web-browser interface, or alternatively one can download the Vidyo desktop client (standalone application). However should you need to upload material to the agenda, a CERN account is needed. CERN provides lightweight accounts to non CERN affiliated people when needed. See https://account.cern.ch/account/Externals/
You are very welcome to extend this website and add information to it. You can find instructions on how to do it here.
The HSF provides a S&C knowledge base at hepsoftware.org cataloging software in use by the community, who uses it, etc. The knowledge base relies on community input if it is to become comprehensive and useful. Please add, update, elaborate, correct entries for your favorite software packages, experiments, etc. All are welcome and encouraged to add and edit material.
