This is a friendly reminder that preliminary proposals for Birds-of-a-Feather (BOF) sessions during the upcoming IETF 113 meeting are requested by 21 January 2022. If a proposal needs further work, the IESG and IAB will work with BOF proponents up until 4 February on revisions, but the initial proposal should be receive by 21 January. IMPORTANT: BOF proposals are now made via the IETF Datatracker at https://datatracker.ietf.org/doc/bof-requests. Additional instructions for submitting a BOF proposal are available at https://ietf.org/how/bofs/. Please also read https://www.rfc-editor.org/rfc/rfc5434, "Considerations for Having a Successful Birds-of-a-Feather Session", if you are not familiar with it. BOFs are just one of a number of ways of bringing new work into the IETF. If you are considering a BOF request but you are unsure whether to submit it, please tell the IESG now by sending an email to iesg@xxxxxxxx, or speak to an individual Area Director (https://www.ietf.org/about/groups/iesg/members/) about your idea. Thanks (and happy holidays!) Lars Eggert IETF Chair
