COLT 2021 will be a hybrid conference with both virtual and in-person components. The virtual part will be held on gather.town and will be accessible using the following link with the email ID used for registration: https://www.virtualchair.net/events/colt-2021.

Authors will contribute a recorded talk, participate in a virtual poster session, and contribute a recorded lightning talk with live Q&A.

Plenary and invited sessions will have live talks. The lightning sessions will feature a re-play of the short recorded talk, along with a live Q&A from virtual and in-person participants. Authors may conduct their Q&A locally or remotely.

The conference will include opportunities for: experts to engage including poster sessions, recorded talks, Q&A, and informal discussions; showcasing the breadth of research in the community with proceedings and plenary talks; and community connection and socializing in both virtual and physical spaces.

We are putting the following precautions in place for the health and enjoyment of local participants as well as staff and volunteers:

• All local attendees will affirm that they are fully vaccinated prior to attending. We ask non-vaccinated members of the community to join the virtual experience.
• Local attendance will be capped at 200 people, perhaps fewer. In particular, the auditoriums will be at no more than half their seating capacity.
• All meals and breaks will be outdoors.
• We are working to provide live viewing screens outdoors. Any participant is welcome to watch any talk from the outdoor area if they prefer.
• Poster sessions will be virtual-only. Local attendees will participate from their hotels/accommodations in the morning before coming to the venue for talks and outdoor socializing. We are working to have technology or assistance available for anyone who might need it for the virtual poster sessions.
• Afternoon social activities such as discussions or roundtables will take place partially or entirely outdoors in the tent.
