kolektiva.social is one of the many independent Mastodon servers you can use to participate in the fediverse.
Kolektiva is an anti-colonial anarchist collective that offers federated social media to anarchist collectives and individuals in the fediverse. For the social movements and liberation!
Just downloaded Whalebird for Windows (Other versions available in your different platform app stores). It allows me to have Friendica and Mastodon in the same program (plus other fediverse instances).
