I know this is like the blind leading the blind since so many of us are new to #mastadon but here goes... How to go about creating a group or topic that is of interest to me? For instance, I'd like to start a group/topic about my state #Pennsylvania or even my town #YorkPa. Maybe even my favorite team the #BaltimoreRavens. I'm guessing however that would be like creating an #instance or #server. Is that correct? I'm guessing its not like just starting a group on #facevook. Any thoughts?
