[Please accept our apologies if you receive multiple copies of this message] *Call for Conference Bids: UMAP 2025 and Beyond - ACM Conference on User Modeling, Adaptation, and Personalization* Dear Colleagues, We are excited to announce that the UMAP conference series, sponsored by ACM and coordinated by User Modeling Inc., is now open for bids for hosting in 2025 and subsequent years. For the 2025 and 2026 editions, we are specifically seeking bids from regions outside of Europe, but all proposals are welcome and will be reviewed. *Expression of Interest in Hosting* Should you be interested in organizing and hosting ACM UMAP, please reach out to Ludovico Boratto at ludovico.boratto(a)acm.org and Cristina Gena at cristina.gena(a)unito.it. We will provide you with detailed information, including the official guidelines. *Financial Details* Please note that while ACM assumes all financial responsibilities for hosting UMAP, they require a comprehensive bid that includes budget details. This necessitates initiating preparations nearly two years ahead of the conference. *About UMAP* UMAP typically attracts between 140 and 190 participants. Both UM Inc. and ACM offer limited funds to sponsor PhD students wishing to attend. However, to ensure robust student participation, we encourage potential hosts to seek additional sponsors. *Support from UM Inc.* UM Inc. works hand-in-hand with the chosen organizer, assisting in the selection of general and program co-chairs, as well as other key roles. We also collaborate on practical aspects such as finalizing dates and structuring the conference. *Submission Deadline* Please submit your bids via email to Cristina Gena (President) and Ludovico Boratto (Vice President) by December 15, 2023. Warm regards, Ludovico Boratto Vice President, UM Inc.
