Anyone can join!
I'm not that great at Mario Kart, despite owning all the games (though oddly, I ended up buying or re-buying them in the past year or so). I did thoroughly play through Mario Kart DS and Mario Kart Wii, though, so I think I'm struggling with 150cc only because I haven't really had much time with Mario Kart 7...too many other games to play. So I haven't unlocked many characters or even many parts yet... >_<
Is there any easy way to "farm" coins?
Anyway, I'll try to at least play a bit of it each day, or else my skills will just get rusty. I don't know if I'll have a regular time that you'll expect me to be on, but obviously it's not going to be before 5:15 PM (Mountain Time) on weekdays, as I do have a full-time job...but if I work out a good time, or if you catch me by chance, I'm up for some races.
