All the policies, procedures, and forms required for presentation of your work at SIGGRAPH 2008:
If your submission is accepted by SIGGRAPH 2008, You must review your permissions (part of your original online submission form) and complete the Acceptance Agreement by entering an electronic signature, within two weeks of your acceptance. If you do not complete your Acceptance Agreement with an electronic signature, your work cannot be presented at SIGGRAPH 2008.
The Acceptance Agreement is a legal document. It explains the uses SIGGRAPH makes of presented material and requires you to acknowledge that you have permission to use this material. This may involve seeking clearance from your employer or from others who have loaned you material, such as videotapes and slides. The agreement helps prevent situations whereby SIGGRAPH 2008 presentations include material without permission that might lead to complaints or even legal action. In addition, this agreement asks if ACM SIGGRAPH may use your materials for conference and organization promotional material in exchange for full author/artist credit information.
