Registration Information

General Information

Register for COLT 2021 here: https://www.eventbrite.com/e/colt-2021-tickets-158605562507.

The two options are (a) Virtual-Only Registration, or (b) In-Person and Virtual Registration.

For students, virtual-only registration is free and in-person-and-virtual registration is discounted. Students will need to upload documentation of their student status, which can take the form of their ID, transcript, or a letter.

Updated: The regular-rate registration deadline for in-person attendees is August 5, 11:59pm US Mountain Time. After this, late registration will be available until August 13 at an increased price. Virtual-only registrations will be available throughout the conference with no price changes. However, registration in advance is strongly recommended, as there is up to a one-day delay between registration and virtual access to the conference.

COLT attendees are also encouraged to attend the COLT 2021 Mentoring Workshop which will run in conjunction with other all-virtual COLT events. Fill out this form to register for free.

In-Person Registration

Due to COVID-19 precautions, we ask that only fully vaccinated participants come in-person, and we have additionally limited the in-person attendance to 200 people. At this time we do not anticipate that registration will sell out.

There will be no on-site registration for COLT this year. The general pool for in-person registrations will close August 13 (anywhere on Earth).

In-person registration includes access to all virtual events. Please see the virtual site for more details on the in-person-and-virtual experience.

See the Local Information page for information about travel and accommodations (e.g., block hotel rates), as well as some local tips.

Authors

Each paper has one reserved in-person registration slot. Please check your email for instructions. We will ask you to fill out a form to indicate which of the authors will claim it, if any. That person will then receive a registration promo code to claim the ticket (and slight discount to clarify which ticket to select). Open problems will also be granted slots once those notifications go out.

Other authors are welcome to sign up for in-person-and-virtual or virtual-only registration through the general pool.
