I am newer to Android, but and am attempting to add group chat functionality that would be similar to the GroupMe app. Within GroupMe, a person can make a group, invite friends and all those friends can share content and see the message updates of other members. I have researched Scringo, as it is a free implementation of person to person chat, but the docs on Group chat imply only using 'chat rooms', not personal small group related chats such as in GroupMe.
Is there a possibility of customizing Scringo so that one can enable such 'private', invitation only, group features?
