What type of clubs did you create using the club system?

Got the EP less than a week ago, so still getting used to it. Mostly having social clubs for teens and YA to hang out and get more acquainted, but also some career or skill/interest related. In addition I use them for community administration and find it useful that when pointing at a sim it shows if s/he has a community assignment. I wanted to create a scouts club, but uniform/warm/cold weather is a challenge. Planning to create a singles traveling club.
