Bryant White :
I see a blue link to the left but not to the right unless it's a Post An Answer Button and I don't see an alert triangle
OK, see the row of square buttons at the bottom right of every post? Should have things like a 'BB' button, a set of quote marks with a plus beside it, and a triangle with an exclamation mark in it (that's the report abuse button, which is sometimes called alerts, because that's what it's called on the Mod end of the system). To the left of that is a bit of text that says "Reply to <username>".
Click the blue link, then type your text below the block of stuff in the box already. Then hit Answer.
