<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Congratulations on your appointment as Conference Chair for the upcoming HotStorage '26: 18th ACM Workshop on Hot Topics in Storage and File Systems. I wanted to take a moment
to introduce myself as your ACM contact for site selection and hotel negotiations.</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">As Program Coordinator for Site Selection, I’ll be your primary point of contact at ACM for all aspects related to hotel sourcing and contracting. As the legal and financial
sponsor of HotStorage '26, ACM must review, negotiate, and sign all hotel contracts related to the conference. This process not only ensures compliance with ACM’s policies but also allows the conference to benefit from ACM’s strong negotiating position as
the sponsor of more than 195 annual meetings each year.</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Now that your Preliminary Approval Form (PAF) has been submitted, we can begin the next phase—defining your meeting requirements. These details are essential, as they form
the foundation for the Request for Proposal (RFP) that will be sent to potential host cities and venues. The more accurate the meeting requirements, the more effectively we can identify properties that best fit your conference’s needs.</span><o:p></o:p></p>
