Any easy way of changing to a custom map on 3, or do i need an admin?

Got the map list up no problem in the consel, just that everytime i select one i end up getting sent to the menu screen in L4D, didn't know if there was an easier way to get the custom's started.

Had a go at Death Aboard last night in co-op. Nice map that gets better with each stage. The Finale is especially good with multiple places to make your stand. Also, it has a sweet form of transport to make your escape in (although never managed to complete it). Not tried versus on it yet, but looking at the layout of the stages I can see it being good for smokers and hunters.

If anyone's trying versus give me a shout.
