Profile generation on LAN?

[MIT_Service]

Hi everybody.
I want to play ET on a LAN in about 2 weeks but there is one issue that I still can’t figure out.
The first time you start ET you have to create a profile and you need an internet connection for this. The Problem is: we won’t have Internet access on this LAN. How do we create profiles then?
It is possible to connect to LAN servers without creating a profile (by console) but then you can’t access the settings menu.
Do i have to create some ‘blank’ profiles for all the people while still at home?
Or is there any simpler way of doing this?
