Not sure if this is the right place and not exactly a bug but...
If I turn on source editor I can use things like <u>these </u>. ( I don't know enough about them to know the names). Then when I turn it off again I see my text underlined.
However, it doesn't show like that in the preview or when posted.
This is probably intentional (keep formatting options simple and not many options) but if you're used to using those commands then it might get confusing.
Any chance formatting options in html will be expanded? (So there will be an underline button and a bullets / list button?)
