## 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.
