Most active bloggers and some more questions

Hi. I'm trying to create a theme for CS 2.1 and I need to show "most active
bloggers" list (with avatars and number of posts) on the main page. Tried
to search here and over the web but still got no results. Can this be done
without writing a control?

 

 Another question is about page titles. I modified Default.aspx in the root
directory of CS with this code:

<Blog:AgedPosts runat="Server" PageSize=5
id="AggregateBlogPosts" EnablePaging="false"
EnableTitle="false" />



It seems to work fine but I get "Community Server - Blogs" in the page
title. How can I use the default one for the main page? And can I limit the
number of posts shown?


 

And the last one... Can I show the most recent photo of the gallery on the main
page with it's description, username, uploaded date, etc? I found this
somewhere:

<Galleries:AggregatePortalPictureListing EnableTitle="false"
Count="1" SortBy="ThreadDate" runat="server"
ID="AggregateGalleryPosts1"/>

But I still have no idea about the way to show the photo attributes mentioned
above or use my own output format (this is not a big problem, I solved it with
CSS).

 

 Any comments will be appreciated. Thanks a lot.
