It appears that Winona State has recently implemented a new policy that doesn't allow non-WSU PCs or Macs to connect to its network. This means any previously installed VPN clients no longer work, and no VPN software is no longer available for PC or Mac.
Due to this change, I will give you a couple options for homework submission. The first is to submit to the class store as described previously. This is the preferred option, but means that you will need to use a computer on campus to submit the homework. If this isn't feasible for you, you may submit the homework via email. Instead of the using the folder name given in the homework description, use this as the subject line for your email as follows:
