Eventually, the series evolved so that most meetings were of this general meetup nature, with only a minority of events having an agenda. Participants are still encouraged to present or raise any subject, and can request in advance that an episode is set aside for such.
 
The events are held at 16:00 UK time, every other Thursday on even-numbered [[wikipedia:ISO week|ISO week]]s. The current week number can easily be determined using Dyalog APL: <source lang=apl inline>⍬2⊃¯11⎕DT'Z'</source> gives <code>{{CURRENTWEEK}}</code> this week.

=== Iverson Centenary ===
On 17 December 2020, a special webinar was arranged to celebrate the 100th anniversary of the birth of [[Ken Iverson]]. Around 200 attendees from around the world attended as the panel consisting of [[Roger Hui]], Leslie Goldsmith, Rebecca Kelly (of KX), Devon McCormick, [[Morten Kromberg]], Simon Garland, and Stephen Taylor reflected on their experiences of working with and learning from Iverson. The legacy of [[Iverson Notation]] for APL, [[J]], [[Q]] and [[Family_tree_of_array_languages|other languages]] was discussed, together with the future of Iversonian notations.<ref>BAA Editor.

After a consensus at the September 9th 2021 webinar, BAA headed an effort to adopt a universal vendor-agnostic logo for APL. This work concluded at the 2022-05-19 webinar.
