Some of you will have seen this already, I'm sure, but this page at Indiginus offers a downloadable pdf-document with the most popular guitar chords transposed for piano. Find the file underneath the freebies:

This is really handy.  Thanks for the link.

Useful, thanks Fleer 

Schweeeeeeet!!!

Thanks Fleer...there's another freebie there as well!

Nice one. This will be really useful.

Very useful for me as well, although I would use it in reverse!  I play the guitar and not the keyboard.  I have a MIDI guitar that I use.  I broke my pinky finger on my left hand and I am unable to use it for guitar...Making a lot of 7ths, 9ths and bar chords impossible.  Using this, I "could" use a keyboard!
 
 

Fleer, nice !
Thanks for the link, I'm on the Indiginus site a lot and never noticed this.

Same here, Bruce, never saw it before. Just browsing and ... voilà :)

Indiginus has a viola?
