Displaying Interest?

<p>Hello everyone</p>

<p>I was wondering what the best way to show interest in a university is. I have been able to visit most of the colleges i will be applying to, but some of these tours have been "unofficial" meaning my parents and I just wandered around campus and into some buildings, but weren't given an official tour. Is there some way to mention this?</p>

<p>Also, does emailing a professor help? What would one even write about?</p>

<p>I have checked and most if not all of my colleges do take into consideration interest during the admissions process.</p>

<p>Thanks in advance</p>
