Welcome, Emmanuel! A lot of people get introduced to additional ideas of effective altruism through the virtual programs, through 80,000 Hours, and through various country or regional Slack workspaces. I don't know of any chat groups or Slack workspaces for Uganda or to East Africa, but you might be able reach out to other people to ask. There are also some cause-specific groups, like Hive for people interested in animal welfare.

Since EA is a loose community rather than a formal hierarchy, I encourage you to reach out to people. If someone wrote a post on the EA Forum about something you are interested, send them a message to ask if they have recommendations for how you can learn more, or if they know anyone you can talk to get get more involved.

Glad to have you here.

Welcome Emmanuel! You might want to post on this thread to introduce yourself, and/or ask any questions you have,
