[Contrib: Evaluation System] Evalsys generating report on > ~75 groups not working

[Will Humphries]

I think the links to the external reports are GET's with the 75 group 
id's at the end of the url. You may be running into a url length ceiling 
in the browser, or somewhere else. Maybe check apache logs to see if the 
request is getting there? I thought the submit button to get to the 
web-based report actually used GET too, so I'm not so sure I'm on the 
right track.
