Once all players have fully entered the server:
Open console by using the tilde key (~) then hit "shift" to open the full console.
Type /pb_plist, hit enter and use the "Page Down" key to scroll to the bottom.
All the players names and GUIDs will be in blue.
Then type /screenshotjpeg and hit enter.
That will take a screenshot of the GUIDs and players.
Then type /record matchdate and hit enter. Actually enter the date as 6 numbers (042809).
After each match half and at the end of each map, hit the F12 key to take a screenshot of the scores.
F12 will only work if that is what you have bound to take a screenshot. The game sets that key by default.
All screenshots and demos need to be saved at least 2 weeks per TWL rules.
