[Dark Byte]

have a database with messages
have a website with phpbthat can access that database
then use getInternet() to get an internet connection and get url's rhat trigger reads or writes

You have to set up a server first,
then you have to build your own chat server code or use existing ones, but in the end you still have to write your own chat code to allow your trainer to interact with the server.

then by using internet you send messages and fetch new messages or send commands such as clear (purge data) or global messages if you wish.
it requires lot's of work but if you feel like your project is finished and needs a chat built-in go a head and feel free to ask for help.

I already did a chat system with Cheat Engine, but I lost the project.
It is like DarkByte spoke, you need a server with database and a server language like php, messages are passed and received from the server per http request, to make things easier it is good to use json.
Cheat Engine supports cookies which is good for account systems.
It is not easy but perfectly possible.
