FOSS gamedev and creative worlds

I cannot find the folder in which MineTest stores worlds, which I need to transfer a world to another computer that will act as a server. My Computer runs Ubuntu 15.10 and MineTest 0.4.12 (downloading 0.4.13 update later today). I have checked the /usr/share/games/minetest folder and done a search for "worlds," but cannot find anything.

Any help would be appreciated. Thanks.

It's probably stored in your user home folder in the ".minetest" directory.
Or simply:

Thanks I found it.

Can't believe I didn't look there in the beginning, since that's where I always find "program files."
