No disrespect intended to oneeyedjohn but I disagree a little.
If you do a search (wedge play, backspin, etc) there are lots of people who post very good information on the regular forums.
I have gleaned a lot of great info from these boards and it has helped me quite a bit. Wish I had read some of it on day one and it would have helped me more and saved me some credits.
I am sure some cc boards are stock full of info too but you can only join one and you may join one that does not have a helpful forum.
