Back when I joined about almost 6 years ago, we used groupme for the chat. It lasted all through my highschool days until something went really wrong to where I had to make a private group aside from the main group. Lately I've checked up on it after getting a private message from an old group member and found out that somebody somehow got into the private chat and ruined everything in it. Not sure if I'll be able to restore it but we lost a lot of amazing members through that incident. So be on the lookout for suspicious members in the chat groups so that they don't ruin what we have for communication between each other...
