Tu = you (singular) Vosotros = you (plural) how does that work out?
Never hear you (plural) form used. I think some refer to it as a proper/Spain kind of thing. Its forms are not only awkward, but how can I use it in the real world?

Do a search on this topic, I'm sure that much has been written on it.
Basically, vosotros is only used in Spain, ustedes is used elsewhere for both the formal and familiar 2nd person plurals
Welcome.
Vosotros is used in Spain to express the familiar You in the plural. Ustedes is used in Latin America for both the familiar and formal You in the plural and in Spain for the formal, plural You only.
