Okay, um, if this is what you mean, to find the editor, you just look for the button at the top of a page. However, it is always best to look at a wiki's rule page before you edit, so that you know what you can or cannot put. Let me know if you mean something different.
Well, of teams, I like Mercedes, since my favourite driver Lewis Hamilton drives for the team; McLaren, since I have hopes for them to improve their speed after switching to Honda engines last year; and I suppose Red Bull for having Max Verstappen being able to break records of being the youngest to do something, and Force India for having scored a few podiums thanks to Sergio Pérez. I also cheer for the slow teams, like Sauber, Renault and Manor, to get into the points so they can improve (especially hope for Sauber to score at least one point in 2016 so that every team has scored points in the season).
