You may want to give each team meeting its own page (using 'Start New Page'). Use the Meetings page to collect links to all the meetings, sorted by date.
On each page, place information such as the meeting agenda, notes from the meeting, supplementary documentation, and action items. Add links to other pages or web sites that are relevant to the topics to be discussed.
Rather than sending around the agenda beforehand, or meeting minutes afterwards, just point people to the meeting's page. Everyone can then make corrections or add additional items, right in the page.
