Each of my team members and I share a ProTask board like this one where we can add agenda items as they pop into our heads, track what we’ve discussed, and assign ourselves follow-up actions.

We have an "info" list that allows us to have a shared terminology for labels we might use on cards on this board. Then each of us gets our own list for topics we'd like to discuss, and finally we've got our goals, actions, and done list to track stages.
