It will take a minimum of 3 years to complete. I am attending the Penn State Mac Admins Conference 2019. Yes No Besides attending the conference, I am also a speaker. Yes No Not at the conference During the Krst three days of the conference, I have already Please take this survey to temporarily deflect your attention from any and all deficiencies of this session https://forms.gle/YhWXcZBsrb3LJTfr9 (https://forms.gle/YhWXcZBsrb3LJTfr9) THAT SUCKS!
