Logging Community Service Hours?

<p>I'm going to be taking part in some community service this summer. I see that several people here list community service hours in their college resumes. My question is, do I need to fill out some type of log of the hours with signatures that authorize that I completed them? Or do I just list them on college applications without any verification?</p>

<p>Have the person who organizes whatever type of community service you’re doing to write a signed letter with your number of hours.</p>
