Present one of your (most interesting) use cases this week. It is particularly entertaining when two (or more) people present the use case together. One speaker represents the system - remember just one, because the system is a black box at this stage - and the other speaker(s) can represent the actor(s). It is okay if you want to have just one person say it all instead though.
Be sure to tell us your recent progress, to-do items and problems as well.
Do not include the use case description in your written report. We can read that and much more in your Requirements Analysis document. Just tell us your progress, to-do items, and problems as usual.
