Tutorial three is up

[Xinfu]

- Tutorial three is up. Have a great weekend!

Does UP make sense? What does it mean?

[poli]

It means over (finished)in this case.

I read it differently than poli: when I read it, I interpreted it as "Tutorial three has been uploaded to the appropriate server/web site, and is available for you to download."

We upload files/videos/audios/documents to a server or web site. When they are up (on the server or web site), they are available for other people to download (retrieve) and use at their convenience.
