I just joined and have become very frustrated because there is no way to practice putting. I found the closest to the pin was great to learn about hitting irons and woods, but aside from playing a full 9 holes there's is no way to work on my putting. I can get to the green in 2 on a par 5 or par 4 and then 3 or 4 putt. Really discouraging guys!
I know this is not what you are looking for, but you can putt 8 times on a par 4 and 9 on a par 5 if you get there in two, just putt away from the hole to the distance you want to try, not a perfect fix but it helps.
