Let's Chat web app requirement specifications

In this section, we will discuss the requirements for developing our Let's Chat web application in ASP.NET Core 2.0.

As a user, I should be able to fulfill the following requirements for this chat room app:

1. Register myself in the web app
2. Log in to the app
3. Reset the password in case I have forgotten the old one
4. See a list of all the currently logged in users in the chat room
5. See a users joining or leaving the chat room
6. See the display pictures of logged in users, if they exist
7. Chat with all online users at the same time, just like a chat room
8. Access the app from a browser over the internet and chat with any number of online users

To give an example, we are looking at a highly trimmed down version of something like https://gitter.im/dotnet/cli, which is a chat room for .NET Core command-line interface (CLI) tools.
