Does Lemmy support some sort of tagging option? So you could post in uni and tags with RMIT or similar, or trains, then tag Adelaide when posting the articles about the Belair line having rock collapses a few times a week

I disagree, (as a uni student) - the types of discussions in these communities are specific to each uni (staff drama, course selection, urban legends, etc) and not fit for an Australia wide community, where the only commonality might be HECS news
