I just spent about 20 minutes reviewing the new site, adding my avatar and trying a sample post with pictures. Great job on the new site. I like how it loads much faster than the old site. There are a lot of interesting new features I look forward to using.
Here are a few things I noticed while viewing the site with Internet Explorer 7 and Firefox 3.0.5. I believe the viewing experience is a lot better with Firefox. With IE7, the text size in the thread list is tiny. I could not find a way to enlarge it. With Firefox, I can use zoom to make the text larger, although this pushes some of the page off the screen (mostly the ads - which take up more screen real estate than the old site). I also noticed that the size of the youtube videos is a good bit smaller in IE7 than Firefox. These differences were not apparent with the old site.
In the few minutes I spent trying a sample post with pictures, I noticed that that "preview post" from the old site is missing. Perhaps the full page editor is meant to replace this feature but I was not able to get it to work correctly. When I attached the image below from my harddrive, the picture was too big for the window when viewed in the editor. I could not tell whether this is how it would look once I posted the thread. Before I post a trip report with pics and videos, I like to see exactly how it will appear.
