I also gave it a try today on those challenges, and I think the current explanations are very confusing.
From http://beta.freecodecamp.com/en/challenges/basic-node-and-express/introduction-to-the-basic-node-and-express-challenges I see we are supposed to start a project on Gomix by “remixing” and existing template.
This template seems to already have some things in the “server.js” file which will allow the fcc website to grade your work. And the file “MyApp.js” is were you are supposed to write your code. However, if you jump directly into the “meet the node console” challenge, there’s no information about this. Since we have a Map, it is expected that some campers will be jumping around from challenge to challenge not always doing things in a linear way. So it should be explained on each challenge section how to start from the Gomix template.
Then the second confusing part is, which link does fcc want?
The project editor link? https://gomix.com/#!/project/something-something
Or the live project link? https://something-something.gomix.me
Or the invite collaborators link? https://gomix.com/#!/join/some-huge-number-thingy
It is not obvious to me which one to use. After trial and error I know that it is the live project link. This should be explained in the challenge description.
