@VPHRAntifa@mas.to Welcome! There are some things on Mastodon that work differently than other social media sites, but you'll get the hang of it soon enough.
Be sure to post (and pin) an #introduction post--with hashtag, and you can pin more than one post here--so that people can find you. Indeed, intros are one of the times that cramming hashtags (your interests etc.) is considered totally appropriate. And be sure to search hashtags to find people to follow.
