We have around 200 subscribers on this list, so when you are thinking of posting a message to the list make sure it is something that is suitable for all audiences and of interest to all, or at least most, of the people on the list. Since this is a rocketry group almost anything to do with rockets, your own or someone else's should be fine. Discussions of launches, meetings and other club activities are also on-topic. There are certainly other things that will be of interest to the majority of the people on the list, but give it some thought before you hit send.
Marking a Message "Spam" Might Automatically Remove You From the Group
If you mark a message from this group (or any groups.io group) as spam, either intentionally or accidentally via your email's spam filter, the system may automatically remove you from the group. Check your spam folder regularly, and never delete a groups.io message directly from your spam folder (move it to your inbox first). If you are removed, check your inbox for a resubscribe link.
If you don't wish to read a particular topic just delete the messages or use the "Mute This Topic" link at the bottom of the message.
If you need to unsubscribe from the list, or make other changes to your subscription, you can do so by following the links found at the bottom of every message from the list.
