WordPress MU

on wrodpress.com they have a nice list of 10 latest blogs. I was going to code one for my site but on looking at the database structure i was stumped!

the url is no problem to code but the NAME of the blog is in a personal table which is built when the user joins - for instance wp_45_options.

How did wordpress.com achive this? AND before i go to the trouble of coding something, is there already a plugin or script that can be downloaded? (lazy bugger you see!)

thanks

There is a builtin fuction get_last_updated(). This has also been discussed in several threads. I quick search will get you several other ideas.

Those are actually the top blogs for the day by traffic, using a modified version of blogs of the day.

Any chance of sharing the code ;)
