Gnet, a couple of questions

Hi, I'm new to BMax and i'm trying to sort out the Gnet commands.

Using the sparsely commented example, i've managed to coble together a basic test of a combined client and server.

What i'm having difficulty with is working out how to determine when a client drops the connection and how to determine when a client has connected (so I can bring a dialogue up to ask if a connection is ok).

Any advice would be appriciated, cheers.

Got some questions too.
Anyone could explain Gnet a little more?
Is it a Server Mark is running? Where? 7/24?
Do i have to take Gnet as something like poor mans Gamespy?
What are the main advantages of GNet?
Why i would use Gnet to provide players position etc. instead using Gnet just to provide the IP adresses of Client and Server (so they could get together).
How much players such a Gnet could handle (lets say for data you have to transfer in a shooter)?
