We just announced a chat with the IE team on the team blog at http://blogs.msdn.com/ie/archive/2006/02/07/526980.aspx

This is going to be fun and I'm forecasting a busy hour. There will be a 500 person limit on the number of people allowed into the chat room so that it remains responsive and manageable. This means that some people might not get in if we get busy and those that do get in may not get all their questions answered. We'll be doing our best to answer questions from a wide range of people on a range of topics.
A lot of the frequently asked questions are already being addressed on the team blog where there have been many posts over the last week or so along with responses to questions in the comments from team members. So take a look there first if you do have something to ask. If there’s something particular that you’d like to see answered then let me know and I’ll see if we can address it either in the chat or as an entry on the blog.

Thanks
-Dave
