Moderating clubs is quite inconvenient when there are a lot of members. When you need to kick someone out of the club, it's very difficult to find them in the general list. Please add a user search in the Members section. And I suggest adding a “Remove User” button, as shown in the screenshot. So that you don't have to search for a user, but immediately delete him or her from the Recent Activity section.
This will make it very easy to moderate clubs when you need to kick a person out.
