One of the things I like about IE 7 is the tabs.  I have my settings so google opens in one tab, and NAT in the other.  When I want to make a link, I only have to switch to the google tab and find the address, then copy it and return to the NAT tab.

Used to be, I would loose my reply when going to google to find links, have to start over.  Using tabs instead of back button prevents the post you are making from being lost, and allows you to insert multiple links and pictures.
