OK I've done this so far. . . (been reading Permission system)
It's hard to know what the options are as I'm not sure of any resources to check apart from this forum and all the available options don't seem to be listed. . . (a comprehensive set of examples would smashing:)
I guess currently I would like to know;
1. if it's possible to turn off the console for users? (I guess this is my most important question)
2. if it's possible to set it so that you can't destroy objects/blocks that someone else placed? I see there is destroyblocks, destroyobjects under world permissions but I assume this means for everyone including a users own blocks / objects?
Also, in my server.properties file I've set server_world_disabled_dungeons=underground,underwater,surface but there still appears to be surface dungeons albeit without chests in them?
OK I've deleted database and created a new seed. Seems to have solved that one.
