No, do not mention it in your SoP. This will not get you admitted. Sometimes there is a question on the application that asks if any relatives work at the school. However, if this question is not asked don't bring it up.
My recommendation: just check your email and gradcafe results page regularly and if you really feel you MUST, check the application website once a day.
I am waiting for an email to be sent (mostly because I applied to more than 10 schools, so checking each one individually would be crazy) or for someone to post an acceptance on gradcafe. Also, it is still too early to be doing that even though some are being interviewed/accepted.
I don't like working out because it gives me too much time to think about things, which is bad because I over think and read into everything, so I just end up being more miserable than when I started.
On the results page, some indicated that they received their Wisconsin acceptances via the postal service. Does this mean I have to stalk the mailman for the next 2-3 weeks?
