When viewing an existing post, the "Post Reply" and the "New Topic" button is not as tall as the "Bookmark Topic" and "Watch Topic" buttons. It looks like the "Post Reply" and "New Topic" are <a href=""> links, and "Bookmark Topic" and "Watch Topic" are <input type="button">
In Internet Explorer 11(Windows) and Safari(Mac), they are still off, but by a much smaller amount. The size discrepancy is larger on Firefox.
Longer text is a tight fit. I would recommend ditching the "button" metaphor for the left nav entirely. Using fixed-size rounded buttons with texturing, for something that is clearly a link, feels very GeoCitites to me.
