I'm still new to Lemmy as well, but I think subscribed it what you want. I scrolled through everything a lot in the beginning, once you see a community you like, click on their name and select join.

You can also search for communities and join them as well.

This adds that community to your subscribed feed. Is that what you are looking for?

Have your played any other systems? Back in high school I played Rifts with that group, more recently we are taking a D&D break and playing a game using the Fate system. Not trying to derail anyone from D&D, just curious.
