Remember that conversation we had a while back where I was concerned about people closing each others sessions... Well, someone just closed mine and I'm pretty sure it's happened before. Kind of retarded but I knew it would happen. Regardless, I like the setup the way it is, just thought I would point out that it's happening.

Oh my, like expected

I think the only way to get this sorted is to add optional accounts. So when you have created an account you can only close sessions when you are logged in, but without the 30 seconds waiting time. When you don't have an account everything stays like it is.
And as a bonus this will be the enabler for adding chat in multiplayer sessions :-)
