One area that seems to be neglected in EA is community support for people outside of Europe/U.S.A.
It may be worth supporting wider regional groups for areas with a lower concentration of people interested in EA.
The idea is that over time people will join the groups and if they get larger, country groups can be created. At the moment people sometimes don't see a group for their country or it is abandoned and they are unable to coordinate.
This way people can indicate their interest by joining a group and when someone joins who does want to organise, they already have a network of interested people.
Here are Facebook groups for three regions I think are particularly neglected.
For completeness here are some other groups outside of Europe and North America.
