A chord is made using 3 notes and chords can be made many places on the neck. You have 3 good fingers, so while you may not play chords in the same place most others do you should be able to find a way that works for you.
On the HOME page near the bottom right side is a game Fretboard Trainer. Great for helping people learn the notes on the neck faster than just looking at a book and strings on the guitar. If you find you need or want to play chords in different places you will need to know where the notes are to make chords.
Example: Open D chord is played using strings D, G, B and E.
D is played open
G is played First finger 2nd fret or the A note
B is played Second finger 3rd fret or the D note
E is played Third finger 2nd fret or the F# note.
So the three notes that make the D chord is D, A and F#.
Knowing that means anywhere on the neck you can find D, A and F# close enough that you can comfortably play them you can make a D chord.
