Subject: Registration
Greetings. You are receiving this notice because you have submitted a registration form to attend the 6th annual PrincetonBusiness Strategies Seminar, put on by the Princeton League ofBusiness Leaders. To our delight, we have received more than twice as many registrations this year as we had for previous seminars. If this participant count is correct, Jt will warrant the switching of event facilities from the conference room at the Princeton Town Office, where the seminar is normally held, to somewhere that offers more space.Before we commit to such a change, we are asking all registered participants to please reconfirm their intention to take part in the PrincetonBusiness Strategies Seminar,August 16-19.
Regardless of how many participants attend, the seminar program will not change. The keynote presentation, titled "Expanding YourBusiness Reach Using Social Media," will be given by PamelaAmen, chairperson of the Princeton League ofBusiness Leaders, on the closing day of the event. Other distinguished speakers will include Julia Mooney, LynneBialek, andCharles Fang, addressing the issues of international branding, responding to unexpected supply shortages, and economic forecasts in the age of global warming, respectively.Clearly, you’re not going to want to miss this one!

Subject: Re: Registration
Dear seminar staff,
My name is Jared Fuller, director of overseas marketing with WishboneEntertainment, and I submitted my original registration for the event on July 17. Per your request, I am writing to confirm my plans to attend the 6th annual PrincetonBusiness Strategies Seminar.
However, in the interest of helping you better estimate the total number of participants, I should inform you that I will only be present during the first two days of the seminar. My colleague at Wishbone, Sarah Waitsfield, will take my place for the remainder of the event. She has submitted a separate registration, but I suppose for your purposes you may count the two of us as one participant, since we will not both be attending at the same time.
Thank you, and I look forward to the conference.
