 This year brings challenges, but also opportunities. While we are saddened by the fact that we cannot be together in Salt Lake City, we are excited by the opportunity a virtual format brings us to expand our community. Even virtual conferences have costs, and hence registration fees are a necessity. To encourage new attendees and ensure maximum exposure for our various content presenters, we have made conference participation for conference attendees free while charging a fee for our content providers.
 
 We invite registrants requiring support due to special circumstances to apply for the use of the [diversity and inclusivity funds](/year/2020/info/inclusion-and-diversity/diversity-scholarship) and/or limited [fee waiver funds](#fee-waiver) (as appropriate), which may be used to offset registration costs. This model, while imperfect, aims at making sure that we keep running a vibrant and fiscally healthy conference even during these difficult times. Note that this year (only), the registration will be attached to content-items (e.g. papers, short papers, posters, panel organization, etc.). Only one author in the case of papers, short papers and similar documents which are considered content-items must register.  Workshops and panels are considered separately. For further information, please see our [Registration FAQ](#registration-faqs).
