Thank you to everyone that provided feedback concerning the icons used in thread listings.  We agreed with your suggestions that the various icons need to be more clearly distinguished, so we have rolled out a new set of icons.  Here is the new set:

Icon	Meaning	Explanation
	Read	You have read this thread
	Not Read	You have not yet read this thread
	Popular, Read	You have read this popular thread (a popular thread has at least 15 replies or has been viewed more than 200 times)
	Popular, Not Read	You have not yet read this popular thread
	Locked, Read	You have read this locked thread (a locked thread can have no more replies added)
	Locked, Not Read	You have not yet read this locked thread
	Pinned, Read	You have read this pinned thread (a pinned thread contains information that you should read)
	Pinned, Not Read	You have not yet read this pinned thread
	Popular Pinned, Read	You have read this popular and pinned thread
	Popular Pinned, Not Read	You have not yet read this popular and pinned thread
	Announcement, Read	You have read this announcement thread (an announcement thread contains important information about the topic of the forum)
	Announcement, Not Read	You have not yet read this announcement thread
	Answered	This thread has received an answer
	Not Answered	This thread has not yet received an answer

We have also updated the colors of links used in thread listings, to further help distinguish between threads you have read and threads you have not yet read. 

Thanks for helping us to improve the ASP.NET Forums.
