catzms...when you see an ongoing message in your group, such as a couple of people chatting, all you have to do is click on the "reply" link or button. Basically, just as you did when you replied to this message.
Then you can do a refresh or reload to the page to see anything that has been added including your reply. If you don't do that, it doesn't appear that anything has been added after your response.
You can do the refresh or reload several ways. Either from your browser's drop down menu, usually under "View". I use Firefox as a browser, so I see "reload". Just click on that.
Or there is a circular arrow that usually means reload current page:
Click on that and it will refresh the page to include any additions if some were added.
You can also do a right click of your mouse and you should see either "reload" or "refresh". After you see that you can then scroll down with the mouse pointer and do a left click.
On most computers you can also do a Ctrl+R and get the same results.
That's how you can keep up on all responses in an ongoing message. Just jump in and start participating. Once you start, you will see how easy it is.
