Good to know I am not the only person who couldn't link turns for a while. In my case I was not keeping my weight forward and staying square with the board. I had a lesson that helped me and after that I could turn without problems. If you can take a lesson, the instructor can probably point out what you need to correct. A stupid thing that helped me stay square (not twisting or leaning back) I learned in a lesson. Imagine you have two little penguins on the edges of your board. Keep your hands on their heads when you ride to practice staying straight with your board. For a while I would just think penguins when I found myself twisting.
And don't worry. Even people like me who took forever to get the hang of things can get to be pretty good riders.
