I made this cool rollercoaster located at our base (1200 1500, we're the southernmost portal in the nether), feel free to take a look and try it!

Whoa, that's extremely cool; thank you for sharing! I look forward to trying it on the server. I'm particularly impressed that you not only made a roller coaster of tracks, but also decorated it to look like a complete structure rather than just a line of rails. Keep up the excellent building work.

I took a ride yesterday on the coaster but it wasn't finished yet. Here's screenshots of the ride I took today. Great job! Love it 😁
