No, I was putting cobblestone down, smash, repeat if deeper :-$
Sand would make it much easier!

Right, I have setup permissions and essentials and I think I've set them up right.

So far from the Essentials command list you regular users have...

/depth - Gives you your current block depth
/getpos - Current coords
/back - back to last place and back to safe block after death (might be issues with this, tell me if there is)
/list - list of current logged in users

It's been a productive day at work.

Want anything else and I'll look into it.

I'm also toying with the idea of allowing people to warp but only me being able to set them.

So I can give you maybe 2 warp spots each and I'll tp to you to set/change it.

Though this will obviously only work when I'm online and I can't see a way to enabling warp setting and having a limit. That would be the ideal situation.
