Ancestry DNA contacts

[Phoenix]

Best mate now has nearly 450 PAGES of DNA contacts. And no computer.
I can see where the relationship lies for some of them, even if their research does not go back as far as hers does.
But is it worth making the contact in those cases? She hasn't a computer, so I'd be doing the slog.
My gut feeling is that unless the family is really exciting, I leave well alone.
Also, has anyone found a way of marking the contacts, so you remember how important each is, and why? I'm adding notes, but this doesn't seem the most efficient way.
