A few people have asked about leaving comments in the network, so here's a quick tip.
You might have noticed that often new comments appear with an indent underneath the comment they relate to, rather than in a long list one under the other. That's because comments in the network are 'threaded', which means that they appear like a tree, with each comment visibly attached to the entry it belongs to. This helps make conversations easy to follow.
Here's an example of comments that are threaded - you can see each one is underneath the one it relates to, and is also indented (the dotted line on the left shows which comment each reply is attached to).
To take advantage of 'threading' and attach your reply to someone else's comment, just click on the 'reply' post that is directly under each comment you want to respond to:
A new screen will come up with the comment you're responding to at the top, and a comment box for you to type into at the bottom. Just type your response and click 'save'.
You'll notice that there isn't a 'reply' link at the bottom of a blog post. That's because the 'post new comment' box is right there on the page. Just scroll down to the bottom of the page past any comments that are already there, and type your comment into the 'post new comment' box.
Click 'save' at the bottom of the screen.
That's it -- easy!
