Allow all types of clubs
We would like to use your club features to organize and track activities for our city-wide nordic ski group. But the limit on clubs to only running, biking, and other is problematic, particularly because our members engage in a variety of activities other than just nordic skiing. Please consider allowing clubs to select any of the activity categories your support. (Multiple categories might even be handy, and Other is still useful for folks who want to share everything.)
Additionally, we would love to see any easy option for manually excluding a given activity from sharing with a group. With this, people would feel they had more control over what they shared, and the group would see postings of activities that were more filtered so as to be more meaningful to that group.
