Hi PCZ,
Welcome back! I'll refer you to http://www.cogs.susx.ac.uk/users/mmg.../faq.php#ntgui for this question. However in the current run the GUI is missing. It will be back when the server is restarted next. No files are ever written to hard drive , this is part of the high security / not intruding with user's PC policy at DHEP.
You can also check your stats http://www.cogs.susx.ac.uk/users/mmg...tsRankings.php and there will be more coming soon, such as individual and team effort rates.
