Sorry if this is a dumb question but can someone please tell me what the color of the folder icons to the left of the topic posts mean? I see that a blue folder icon with red, blue and green vertical bars means that the topic is a poll. What is the difference between an orange, blue or gray folder icon? What does gray with a white rectangle on the right side mean? Red with an "x"? Did I miss any?

Thanks for your help.

 

There should be an explanation at the bottom right of each section, labeled "Forum Legend." LMK if it's not there.

 

The legend doesn't show it but any folder with the white paper clipped to it signifies it as a topic that you have posted in. All of those topics that you have posted in can be found in "My Content".
