In the announcement regarding the new features, there is a link for "Sponsors" that takes you to a list of all the sponsors with ads that appear at the top and bottom of the page. I have looked for a list before, when trying to decide whether to mention a particular company in a post and been unsuccessful in finding a list. I like that feature and hope that it either remains - or is more easily located if it has been there in the past.
One thing I noticed, yesterday so I don't know if it's new, was you can select in your preferences to have the "reply" actually there in the email notification you get. So you don't HAVE to click on the link to read it. Of course who wou;dn't click on the link to see what's been goining on since the last time you were on???
