What is a Member?
Members are the people that make up your group that you'll be communicating with. Members include both the admins (who send the notes) and the people you will be sending notes to.
The best way to think of a member is as one set of contact information (an email address and/or phone number). Members can be subscribed to multiple groups at one time and will still only take up one 'spot', so to speak, in your member count.
If you have an individual who would like to receive information at multiple email addresses (say, a work email and a home email) - that will count as 2 separate members if both email addresses are added to your network.
You are able to see how many members you have in your Flocknote by looking at the member count in the top right corner of your Everyone group People page. Everyone in your Flocknote network is automatically added to your Everyone group. In order to remove someone from your network, you must remove them from your Everyone group (removing them from other groups just removes them from that particular group).
