Okay, you've prodded me into action! I'll send round some instructions, 
make some improvements, and build up the wiki information next week. 
Since I'm no multi-tasker, in the meantime please try to finish any 
UNVALIDATED analyses that you own, and generally try to tick off issues 
on the Rivet bug tracker ;)

Have a good weekend...
Andy
