I had same thing go on as well but I couldn't access the survey for some reason.
=/ Maybe I was just having technical difficulties so I tried again the following day (Friday) and but I could not log on.
My two cents into the situation ( could be totally wrong and partially wishful thinking
) is that we're candidates for the English summer program, will be getting our emails around Friday( from last years form and the year before that many people who recieved the english option were received their emails pretty late) and our accounts are deactivate so they could adjust it (since accepted people still have their accounts but their ranks and role have changed) so we could use other features?.
But yeah, very confusing, I wish they sent out an email on what the e-value was for and why everyone is getting instead of a vague email saying "Welcome to University of Colorado SOP".
