Q. How do I write in discussions?
You can create a new topic by clicking the Create New Topic button, which will expand a form that has a topic title and a text entry box.
You will need to give your topic a title, and then add your first post. When you are done, click Submit at the bottom of the page, now you have a new topic!
One other thing you may notice is a drop-down box at the bottom left labeled Topic Type. You will only see this if you are a group administrator. But if you have this, you can choose to make a topic sticky. That means it always appears at the top of the list of topics, even if something newer has been posted. You might use this for administrative topics.
