Athens has a number of clubs and organizations. They can be found as a part of an academic institution, such as a school or a college, or they can be set up independently. They may be registered separately, or be a part of an overarching organization. Many clubs have chapters in a number of cities, such as the Lions Club. They can be general, or focused on certain hobbies or skills, such as a book club or a computer club. Clubs are places where one can have fun catching up with friends and doing activities with them, such as book readings. One can also use more professional clubs and organizations to meet people, interact with them and network with them for professional advancement. This can be extremely helpful. Clubs may or may not charge for membership in Athens, but often a nominal charge may be levied for carrying out day-to-day club activities and organization. Being a part of a club can be both professionally and personally rewarding.
