Hi Mike,
The best way to keep appraised of upcoming webinars is to look at the bottom left of the BAA homepage, where the next 4 meetings/webinars are listed. There is also a full list of meetings and webinars on the BAA meetings/events page.

While the postponed meetings get in the way a bit, the webinars for the next 2 weeks are showing in the bottom left of the homepage.
The next few meetings/webinars are also usually listed in the monthly BAA newsletter. Though with the rapid changes of the past few weeks it has not been possible to know about all of the events sufficiently in advance to get them on to the newsletter, which is why we said to check the events page in the last newsletter.
Sending out bulk emails is a tricky topic. If we send too many we get complaints, and if we send too few we get different complaints, and we have to be careful to keep within data protection regulations.
Best wishes,
Andy
