Actually we have two kind of mailing lists: one regarding the news about the project and one for the support requests.
News
If you subscribe to this mailing list you will receive a mail as soon as a new official version of Health Organizer is available.
Support
The support mailing list let you ask for support about the program just sending a mail to hor-support-en@lists.sourceforge.net.
Make attention that your e-mails will be stored and be public available in our archive. If you are not confortable with this, you can create a new ticket (check Mark as Private if you want nobody, except us, see it).
Please, check the F.A.Q. page before to ask for support. Thank you.
