Many featured of dilo are not immediately obvious. Part of the value of having a community is responding or replying to what someone else has written. Many of you are doing this now.
Here is a tip to make a reply even more "connected" to the original post. If I am reading what someone has written, say when José Luis mentions he is a biologist and studies arthropods, and it generates a thought I want to "dilo", I select a portion of the text with my mouse, and you will notice a "quote reply" box appears.
If you click that (or the normal Reply button), in your editor, you will have that section as quoted and attributed to José Luis. When I add my thoughts, it makes the connection more visible.
Try some quoted replies the next time you respond.
