You can add as many forums as you like. Think of forums as rooms to discuss certain topics in. So for example you could setup the following:
Training - a forum to discuss training-based topics
Finances - a forum to discuss everything relating to finances such as invoices, fees etc
Events - a forum to discuss club events
General - a forum to discuss anything not covered above
And so on
Inside forums are "Topics". Anyone with the "View Forum" permission can create topics.
