→Connecting up everyone's portals: A note on jay's spreadsheet, and a bit of formatting
# Go to Jay's spreadsheet.
# File > Make a copy.
# Answer the question "what information do you already have?" by telling it whether you have your topside or netherside portal co-ordinates.
# Select "I'm digging from the main road to my portal".
# Enter your co-ordinates. The spreadsheet will tell you which colour road to walk down.
# In Minecraft, make it show the debug screen so you can see your avatar's co-ordinates.
# Head to the new y=8.5 nether hub.
# Walk down the road of the colour the spreadsheet told you, and stop walking when you get to the co-ordinates that the spreadsheet calls "Start at these co-ordinates on the road:"
# Build your portal, light it, and step through. You should end up at your topside portal.
# When you head back through to the Nether, you might end up at your old portal in the old nether network at y=13.5. It's safe to dismantle your old portal now.
