What is Explorer Mode?
Enabling explorer mode lets you use features before it goes out to everyone else. You'll get features like collaboration repls and more! Remember that all explorer features are experimental, so there will be bugs and glitches. When you find these, make sure to report them at https://repl.it/bugs
How do I Enable Explorer?
First you need to get to your account settings. You can do that by clicking your name at the top right of the screen and selecting Account or by just going to https://repl.it/account.
Next, click Roles and enable the Explorer check box.
You are now a Repl.it explorer!
