I tried connecting to the server, and I never got to the phase of logging in. I tried connecting to trident.oracle-mc.com but that was in 1.7.10, so I switched to 1.7.10 and never got PAST the logging in phase.
1. I'm used to developing plugins in 1.8, and I have no experience with previous versions of Minecraft.
2. Not to be rude, but if you tell me to join a server, please make sure the server is up.
