I generally find that clubs don't have online message boards or links when it comes to ongoing activities and events. They usually communicate via email or through facebook etc to arrange their activities. At least that is how I do it - when I joined in activities. The links may provide you with a general contact number where you can approach the person in charge or the main phone number and from their own, personally email them or contact them via phone. Many university clubs and community clubs (you'll find them in many residential suburbs) post their events on notice boards as well so it is a matter of you being proactive and looking out for them.
