The UMSU site does not offer links to views that oppose the groupthink of the CFS so I will offer a link to a site that has PROS and CONS to joining CFS:
http://www.umanitoba.ca/csa/CFS.htm
And before anyone says it, yes I am stating an opinion on an internal matter of UMSU. I do so relucantly but I feel that it is fair of me to do. Especially considering that the CFS is spending thousands upon thousands of dollars on the campaign and parachuting in dozens of people who have never attended UofM to campaign full-time for CFS. So I will merely offer people a link to a balanced assessment.
Trust me, I could have done a lot more.
