This thank you note to sponsors was prepared by Brad Vander Zanden for UIST99. A similar letter was sent out by postal mail as well.

Dear Dan, as general chair of this year's User Interface Software
and Technology conference, I would like to express my profound appreciation 
for your company's sponsorship of this year's conference. 
As you know, UIST is the premiere conference for the presentation of
software and technological innovations in user interfaces and your 
company's sponsorship is invaluable in ensuring the success of the conference. 

One of the critical facets of the conference that your sponsorship
helps support is our student attendees. In particular, your sponsorship 
allows us to encourage their participation by 1) reducing the fees for 
students attending the conference, and 2) providing complementary registration
to student volunteers. As you well know, students are our seed corn
for the future. Hence the opportunities that your contribution affords 
them to participate at UIST and to interact with leading researchers in 
the field is invaluable both to their careers and to our profession.
The ability to have these interactions generates considerable good will 
among our members towards sponsors like yourself.

One of the ways in which I would like to express our appreciation is to
publicize your company's sponsorship to conference attendees and to
the members of the ACM SIGGRAPH and SIGCHI societies which receive both the
advance program and the conference proceedings. Continuing the tradition of 
past conferences, I would like to do this by placing your company's name and 
logo on a variety of our conference's materials, including the final printed 
program, the conference proceedings, the conference web page, the advance 
program, and as a slide in the opening and closing ceremonies. Typically we 
devote a special part of each of these materials to thanking our corporate 
sponsors. If you could send me a copy of your company's logo art and your 
company's name as you would like it to appear in these materials, or 
alternatively, point me to an online file containing this artwork, I would 
be most appreciative. In sum, we will endeavor to maximize your firm's 
visibility in our publications.

Once again, many thanks Dan for arranging for this sponsorship and
to Oracle for providing us with this sponsorship.

        Sincerely,
           Bradley T. Vander Zanden

PS Since email is a bit informal I also plan to mail you a copy of this
	thank-you letter. Brad Myers did not forward a postal address to
	me so I would be most appreciative if, with the logo art, you could
	also forward me your postal address.
