I also ran into the issue with the .ics files on the plug site mentioned
elsewhere with the timezone switch horking the schedules in both
evolution on a linux box and iCal on my mac laptop. 

So just so that I have it straight now:

PLUG Dev is 1st Thurs 7-9pm
PLUG East is 2nd Thurs 7-9pm
Stammtisch is 3rd Tues 7-10pm

Is this correct? Are installfests always the last Saturday of the month,
or do they get scheduled on various Saturdays?
