how to add to favorites.
How can I add a server in the main menu of the game?
For example: if I want to add a server:

Name: servexemple
IP 123.456.7.890

I also have another question secondary
what is git?

Just connect to it once and it should be automatically added in the favorite server list.

Git is a version control system which is used by the Minetest project.

I did that, but after restart, it was gone.
Maybe the IP changed?

Or I'm still using an older version maybe.
Using Fedora 19 which does not offer update greater than 0.4.9
