@guludo #welcome to the fediverse! Don't worry there are lots of friendly people here so you can make new friends. I will be your friend if you want!
Also new people are always welcome so invite your friends to join us here! They don't even need to log into mastodon.social to interact with you. Go here: https://joinmastodon.org/#getting-started and maybe you will find birdsite friends on other servers in the fediverse already!
