Welcome! Glad you could join the network!
If you already have friends who use Mastodon, Pleroma, GnuSocial, Friendica or other ActivityPub enabled networks, you can use your Osada connection to follow them! Just ask their address and go to the /connections page. Type in their address and click "Connect". You'll be connected to them. As they converse with others, your feed will also begin to fill up and you'll find more people to connect with and talk to.
Again Welcome! And have fun!
