Seminar Schedule
All lectures will be from 9:00 a.m. to 12:25 p.m.
Please note that there will be no lecture on May 5.
To: Kimberly Ward From: Yasunobu Takagi Subject: Thanks
I felt that your help was very valuable to my presentation. Most of the attendees had come to my lecture for the purpose of learning how to market the goods that they sell on their web sites. Without your input, I' m afraid they would have been disappointed with my lecture. I would like to incorporate some of the data that you have accumulated into my future presentations. I feel that I must change my focus from marketing a site to marketing the contents of a site.
As agreed, let' s meet on May 10th. I have asked Ellen Lee to help me with this as well, so she will join us. I have another series of lectures coming up soon, so I' d like to do this right away.
Regards,
Yasunobu Takagi
