tug23 talk deadline

[Karl Berry]

Hi everyone - although the deadline for submissions of talks for TUG'23
in Bonn this July (https://tug.org/tug2023) was theoretically yesterday,
there is no harm in continuing to accept submissions for some additional
time.  So if you have any interest in speaking, don't hesitate to email
(tug2023 at tug.org). More info: https://tug.org/tug2023/cfp.html.

Please pass this info on wherever relevant ... --thanks, karl.
