"Brainless Practice"...dude, I've spent the last seven years doing nothing but that!...When I first started I thought the Dsus2 was the greatest chrod in the world, (I still think that's true, but for different reasons).

As for learning chords, and anything else for that matter, I've found, (and still find) it's vital you persist. If you can't play F Major at the 8th fret, keep trying until you can. If you can't play Bbm/D - keep practising until you can...I've been playing songs for years and it's only within the the last three to four months I've actually got them right.

The important thing is not to expect instant results. When you see your favorite guitarist playing a solo or riff, what you don't see is the hours of practice that's gone into it...chords are the start; they seem impossible to to begin with, but once they're conquered, the world really is your oyster.

As for actual chord diagrams or lessons to help you learn, search GT for "Chords"; or, try www.guitartabs.cc - where there's a .crd file for ever chord you could possibly need. Let me know if you have difficulties find it and I'll post the full URL.

Hope that's of some use,

Regards,
Chris.
