Q:

Which web part is this? 

When i create a blog site from the blog site template, it automatically adds this web part called "Archives".  Now i would like to know how to add archives, and i would like to know the name of this web part, however when i edit the webpart it does not show the name!  Below is an image to demonstrate my problem.

So my question: Which web part is this?  
Subquestion: How do i add archives to this web part?  
Thanks in advance!  

A:

It's a Web Part called BlogMonthQuickLaunch.  It has no properties and is all generated from the posts list.  
If you need to change this one, you must roll your own Web Part.  Tip: BlogMonthQuickLaunch is not sealed
