[UIC Data Communication Workshop 24S Group Assignment2]

Project Description

Our purpose is to create a chat room that allows local area users to freely communicate with each other one-on-one as well as group chat while ensuring individual privacy.

We also give administrators the ability to manage users and all chatting groups to ensure a friendly chatting environment.

And if users do not know how to operate, we will also have a prompt to guide them through.
