Em-dashes (minus-sign hyphen, 43-17, American-Indian, 43 - 17 ,) -- in Markup -- are possible? This is a test. Double space.

Edit: Dammit. Also testing edit feature. After this will test retract feature.

Edit 2: Retract feature tested. Testing edit feature on retracted comment. Idea: Edited text should be .75 out of 1 on greyscale. Text edited twice should be .5, thrice .25, and then you're done and should be done, why would you need to edit it that many times anyway? This would only apply to editing/addition of words and characters, not spacing or emphasis.

Edit 3: Apparently you can edit text before or after retraction. Not sure if this is a feature or a bug.
