Teams Chatting with others teams inside teamChat how?

I would implement a system that uses .Chatted

When using the signal, you’re going to want to be able to get the player associated with it.

• .Chatted Fires
  • Returns Player Instance
  • Return Message
  • Returns Boolean (true if chat was a team chat)
• Set conditions & variables
  • Stop if Boolean is false
  • Find the Player’s team
• Find the player’s team alias
  • Send the Message as a team chat to the associated team

This is theoretical and not practical, for example only- details in here may be incorrect but the idea is correct.

Let me know if this helps you.
