Newb guide:

First you should read the RuneScape manual and explore the word or RuneSape. Then you should rise your fighting skills a bit. Make some friends and enemies. Try to get some money. Learn which armor is rune and which bronze and so on… Don't train all day, because then this game becomes painful… Play for fun!

F.A.Q:
Q: Where is wilderness?
A: Go north…. make sure you don't have valuable stuff with you.
Q: What if I die?
A: Then you rebirth in Lumbridge. You drop all coins, runes and all your stuff except 3 the most valuable. If you die when you have a skull you lose all your stuff.
