Halp!

I had quite a few questions about the smp server , http://map1.mikes-revenge.net/
so here they are:
Commands?
Rpg thingy? (wars, towns, alliances, cities, etc.)
If there are cities, can we build outside of them? Collect only certain Resources?
Any interesting mods on the server?
Any building restrictions, such as only building in a city/town?
Do we spawn items?
Griefing? (I took it as that was a ban.)
What does get a ban?
Rules?

If there are any more that I can think of, I'll post them.
