VB.net and Internet explorer Communicate?

[itturnstoashes]

I was doing some myspacing, and decided that it'd be so much easier if i could just type in someones friend id instead of navigating to their page, type a comment in a box, then click a button, and have it submit a comment.
I'm willing to use a few webbrowsers inside this app. One for login, and one for post confirmation.
Does anyone know how to make VB communicate with a web browsers form? Any help would be greatly appreciated.
