Well, I know it takes time to build things on the server, and we all have things to do elsewhere

I would hope!
I like the communal hall on Craig's server, as well as the industrial building where you can learn how to use the features of the mod - all close to spawn and protected from griefers.
With the mods, Minetest has the potential to be almost limitless - a true 'sandbox' - and this (someone who's been brought up on linear games) is the most attractive element of it.
What you can imagine, you can build, and share! (technically, what you can convert into 8-bit images you can build on Minetest, using coloured wool and the original image as a grid-map)...... looking forward to doing some of that....
200 block high Sonic the Hedgehog anyone? Someone online has done some awesome 8-bit conversions of Half Life 2, Breaking Bad etc...
Craig, can we put a 'sculpture park' in somewhere? with marked plots of different sizes?
I've got to focus on what I'm already building though - otherwise there'll be half-builds everywhere...
