HPS Software is an email list for asking questions about any of the software being used on the HPS experiment.  It is fairly active with usually at least a few messages everyday.  It is public and un-moderated; anyone can send a message to this list.

Since all of the software experts on the experiment subscribe to this list, and other people may have a question similar to yours, you should generally avoid sending personal emails about software related issues and instead use this list.


To subscribe, send an email to majordomo@slac.stanford.edu with subscribe hps-software as the message body.  The subject can be left blank. 

You should then receive a confirmation email shortly, saying that you have been added to the list.
