Hi Edith,
I'm not entirely sure I follow what you want to do: you can't set the system to switch directly to the email page, but there is an email icon that the track director can click after assigning a review to an abstract or paper; if you have chosen the 1-click review process, the email template will include a link directly to the review so that the review doesn't need to log in and check their queue.
There have been some issues with the 1-click review process, as posted here:
viewtopic.php?f=3&t=2673&p=9520These have been fixed in CVS and so will be fixed in the upcoming release; but if you are having problems, let me know and I can show you what you may need to change.
Cheers,
James
