How to save in Minecraft Pocket Edition?

I built a game in a world for me and my friends to play in, but I don't want to have to "reset" the game every time we want to play. Is there a way to save and "replay" a world?

How to make a minecraft pe server?

Ok so i'm trying to make a minecraft pe server so that me and my friends can all play together. I tried using pocketmine (i alredy port forward it) but you need to be connected to the same Wi-Fi for it to work and they live a mile away. I think that using a vpn could work but i'm not sure. Someone help.

Is lying where donations go fraud?

Ok so on this minecraft server the server makes about $1000 a month. The actual server itself costs around $400 to maintain with all the other services. The owner of the server says that extra $600 was going towards paying someone else to make and fix plugins. While I was snooping through stuff I found out by one of his friends that he is actually pocketing money. He says that all donations go towards the SERVER and he pockets NOTHING. So would this be considered fraud?
