Ability to message a private strider

So, in my last city [Keller], I see this “* A private Strider is in 2nd Place at 99.9%”

I’m at 100%, but would like to know who is at my heals.

Of course I get the privacy aspect, but still would be cool if I could message privately (and keeping recipient anonymous, not sender). Running community in Keller is pretty tight, and I might know this person.

This idea would mesh nicely with the friends idea: Friends list/leaderboard

And maybe, in lieu of friends here, it would allow Striders to connect via other social media sites?

Only thing I can think of, is might need an option to block messages, as maybe some people really do want to be 100% anonymous and invisible.
