@rosei123 Thanks for the follow, and welcome to Fedi!
It can take a bit of time to find your way around. There's a few 'getting started' guides floating around, though I don't have any links handy.
One big suggestion -- make an # introductions post and use the introduction hashtag. Include 5-10 hashtags with stuff you'd like to talk about or connect with other people about.
You can also check out Trunk ( https://communitywiki.org/trunk ) to find folks to follow.
