That magnifying glass icon that you see, is a "watched topic indicator."

If you click on it, you will be presented with a menu that tell you what it is, and a few options:
* Stop watching this topic -- this does what it says, and will remove the icon.
* Do not notify me -- depending on your user settings, this WILL NOT send you an email for each reply to this topic.
* Notify me for new posts -- depending on your user settings, this WILL send you an email for each reply to this topic.

On UBBCentral, you can see your entire list of watched topics at:
https://www.ubbcentral.com/forums/ubbthreads.php?ubb=myhome&tab=topics



The attached image is the menu you will see if you click on that Watched Forum/Topic/User (magnifying glass) icon.
