Ask HN: How do you keep track of your advisors?

Hi HN,

We're putting together our advisor/mentor board right now and I was wondering if anyone had recommendations about how they manage this process. Is there any way you keep track of them? How do you differentiate between them -- by skillsets, connections, etc; and do you use a service to classify?

We can use excel or word for this but I'm hoping there is a bit more of an elegant solution, considering the sheer amount of data that is attached to each connection. What do you use?
