I don't understand all the forms of saving completly yet, but I'm starting to get a vague idea. What I would like for my game is so you can go from server to server with your savefile always the same. Something that would be similar to Duel Monsters Online by Kaijka(To be exactly like that really..)

I was told to do Client Side Saving, and so I looked up the demo and did that. There was one probelm though, it would not save on logout. So this leaves the chance for people to dublicate items and whatnot.

Is there any super special awesome secret method of saving that I don't know about or is this as good as I'll get?
