The editor to enter your discussion seems very limiting.  Here are a few other actions I would like to have available for the details of the discussion...

1. Ability to change the font type
2. Ability to change the font size
3. Ability to change the format of the numbers list (e.g. Upper/Lower case alphabetic, Roman numerals, etc)
4. Ability to have different types of bulleted list.
5. Ability to view / change the underlying HTML so we have much more control over the resulting details.
6. Ability to add a horizontal line
7. Ability to save minor changes that does not send a notification to everyone who is subscribed.
