Add an add comment to both the top and bottom of the idea portal page

When reading through ideas in the ideas portal, if you immediately have something to say you click the add a comment button at the top, but this doesn't feel enough like a conversation or forum, it doesn't flow. It may improve if you add a reply button at the bottom of the comments as well, so when you finish reading all the comments you don't need to scroll to the top of the page to capture your thoughts. A further improvement could be to quote someone's comments or reply to a comment. This way the idea can become a discussion between stakeholders and interested parties.
