Okay... I know it's hard to try to "network" when you're still in college. I know it is. Trust me, I have been there. But here's a tip, for my non-existent college audience: When corresponding with a professional contact, you must, must, must spell the name of her agency correctly.
You should try particularly hard to NOT spell it incorrectly three times.
Especially when you are writing your contact to say that although your campus club has enjoyed its past annual tours of her agency (led by her), this year it would like to tour the sister agency instead, and could she please send on the contact information?
This sort of note will be interpreted unfavorably.
