Yea, I was going to post about this.
I have read HORROR stories from people including Danny Sullivan about installing this upgrade and I NEVER like to upgrade before a new release is stable.
BUTTTTTTTT I really would love someone who already has it to check my main site, blog and forum to be sure everything displays right.
Affiliates really need to test their sites - warnings below:
Warning, reports indicate Ie7 still has trouble displaying some types of CSS and there are other anomalies that could affect how visitors view and access your site. The last thing affiliates want is to find out mid November that people have not been able to view their site with IE7 all month.
I also read that links from Tribal Fusion ads do not work or display at all.
So if I were an affiliate I would REALLY TEST everything before everyone starts upgrading.
Beware, from what I have read so far you cannot keep IE6 after you download IE7 so it will be impossible to do cross browser testing. It will take time for all users to upgrade to Explorer 7 and many like me are hesitant to even download it all all until its stable, so you still need to be able to check your site in IE6. That's another reason I hesitate even downloading and testing right now.
Here is a site that shows you a screenshot of what your site will look like with IE7. I was worried because someone told me the beta of IE7 didn't display my site when they tested it.
My site looks OK now from what I can tell with this
IE7 Preview Tool.
