Local online party in parallel for global during scala3 release party?

Hi, colleagues.
I thinking about creating a local online networking meetup in parallel for global. [Where people can speak in the Ukrainian/Russian languages. between/during sessions and afterparty].

Technically, if the main conference is Zoom, then another parallel conference should be in something other [to allow people to switch without leaving meeting, Zoom ], or maybe conference owners can
create rooms for local communities.

What do you think?
