wpmu question - twitter tools plugin and more

I
have a question about the STAR Educator blogs. I noticed you're not
using the most recent version of WPMU - and I think it's causing some
trouble with the Twitter Tools plugin. You can't set a default category
for your twitters to go in (checked this in IE7 and FireFox3).

I'm not sure if using the older version of WPMU is the cause, but it
may be. Are you guys going to upgrade the blogs any time soon?

Also - who do we make plugin requests to? I'd love to see wp-o-matic
added so we can bring rss feeds in as individual posts on our blog
(saves reposting from personal blogs to here).
