<human>: So, today is my first day of grad school. Yesterday I was on campus checking out the library when I discovered I had been checking the wrong email. 

I have for months been receiving important emails to my gmail and this webpage where I would get notifications of important messages. I thought that this was the email service. I was very wrong. 

Imagine the sinking feeling when I was using campus computers and was provided a link to the webmail services- a link I was somehow never made aware of. When I logged on I was horrified to find 40 emails spanning MONTHS and providing important and time sensitive information. 

As a consequence I completely missed Graduate Student Orientation and a mandatory meeting for my major where I would have met my fellow students and received information. I missed an email that was sent in JULY asking for resumes from students interested in being paid TA's. I emailed my resume last night and explained the email confusion. I got an email back this morning from the department admin telling me all positions had been filled. She also forwarded my email to the head of the department who emailed me about missing the mandatory meeting, that I need to see the admin to pick up info I missed, and that I need to check my email often. 

I'm essentially walking into class tonight having met none of my classmates, completely missing out on an important job opportunity, and behind on information.

Can you provide a brief overview of the text?
<bot>: Didn't realize I wasn't checking my email, lost a job opportunity, probably left a bad first impression on the head of the department.
