hi...is it possible throught punkbuster to capture screenshot of a player?. i think i saw it somewhere and i want to check a player but i dont know how to do it

PBSS is built into the server and is an automated process but you can also manually trigger a screenshot to be taken. If the server is hosted by GameServers, you can view the PBSS directly from the GameTracker page. 

Thank you i will forward it to server admin....hope he knows what to do
