Challenge likers (FitStar & other apps) welcome!

Options
I'm Valia, currently living in Moscow, Russia,
23 years old, a technician (IT field, junior Linux admin & hobby C programmer).
Others often describe me as a very nice friendly person. In fact, I am, and I would like very much to find new friends here. :) You can feel free to write me.
But most of all I would like to find company to participate in various challenges. Say, FitStar app, that supports MFP and automatically pushes into it information about workouts you've done with it, offers also competitional possibilities. Days of workout, calories burned or something else can be counted and compared. I've taken already this challenge alone, but I would like a company very much. :)
Also one of my hobbies is running, so I'd be glad to be invited to compete using such apps as Nike+Running, for example. (The only limitations are: (1) I'm just beginner, and (2) I have only an Apple device (iPad).)

Cheers!
