If you are a registered user of our software you are already on our mailing list (assuming you provided an email address upon registration).
We normally only send a few emails. The first will arrive about a month after you register the software, just to see how things are going. After that, we send notifications when new program updates are available, or for things like occasional server maintenance down-time if you're using our hosting service.
If you are not a registered user and would like to receive release notifications, please contact us and ask to be added to the mailing list.
We never rent or sell our address list to anyone.
