There are many, many different group messaging apps out there. Each of them have their own particular merits, some are more popular in other countries, some allow you to play games or have stickers, and other allow self-destructing message content. However, what all of them seem to have in common is that they put an arbitrary limit on the number of group members. Some of these limits are by design, for example there is an app aimed at couples so clearly the group is limited to two people! When we were designing yagmap, introducing member limits never crossed our minds! This means you can have as many or as few group members as you want.
