Yeah, that is a good idea. Maybe add showing friends through the whole of the three servers (Survival, Economy and Skywars) would be a good idea. Also maybe when a friend come online it says in chat *Hey Eleanora* "Eleanora_ has joined Skyblock.org". EDIT: Also make sure there is a limit to the people you /friend. Maybe Donors can add more friends (20??) than Non-Donors??? (10??)
I mean, I think that donors and non-donors have equal rights. But maybe if you donated 100+ you could get 20 friends. So I'll think about it.
