To you know how a forum works I've set a little task for you.
1. Post a short reply to this post (a hello is just fine for now)
2. Go back to Course Forum and 'Add a discussion' to tell us three things you think are the most important about water in our city and why they are important.
Once you have completed these two steps, a tick will appear next to the Course Forum for you. This will tell me you know how to start and reply to a discussion.
PS THANK YOU Barbara for suggesting a better way of doing this, I have changed it now
