All you have to do is click on your name where it is highlighted in blue on the forum or anywhere you see it and it will take you to your summary. On the summary page scroll down to where it says additional information and click on Show the last posts from this person. You can do this to anyone if you like reading a certain persons posts.
Oh you can also look at the general statistics of each member and it will tell you a lot of information on the member including bar graphs. No I'm not crazy just a computer teacher for junior high kids. You can learn a lot from the little sneaks in Chicago.
Or you can click on Profile at the top and then look to the left handside where it says profile info and it says Summary, Show stats, and Show posts. Click on show posts then click on the subject after RE which is the name of your post and it will take you directly to it where you can see if people replied.
