Roomstash is a simple way to chat online with people on the same network.
When you access roomstash.com into your browser, we create a chatroom specifically for your internet address (known as IP). This way, only people with the same IP as you can access the chatroom.
To make it simplier, just see it this way: one IP equals one Roomstash instance.
But registered users are able to come back on the Roomstashes they visited.
You will be attribuated a new Roomstash instance.
You can change your nickname by clicking on the settings gears on the right vertical sidebar. Roomstash will remember your nickname as long as you are using the same browser session (it works with cookies).
By registering, you will be able to keep your nickname no matter which browser or session you use.
Registered users can join multiple Roomstashes as long as they visited each one of them while having their IP once.
