Goodly

Since MCGalaxy uses C# .net, you can use ILSpy

Don't do this. This is how you get your server ruined by people who pretend to be trustworthy. Seen it a million times If you absolutely must, though, we would need to know what you are using to host exactly to answer the question.

The app you used to brighten it left the edges darker. Meaning there will be obvious dark lines when the clouds repeat. You should use something else to edit them.

Am I correct in reading this code that this displays everyone with the rank advbuilder or higher? Shouldn't it at least default to operator?

Welcome to classicube! I’m assuming you’re in single player since you mentioned flooding. Sponges clear an area of water when you place them which should be the fastest way to remove water. There is also a hax setting called “breakable liquids” (esc menu) that allows you to break water directly by making water target-able. Finally, there is also an option in i believe misc settings menu that allows you to turn off water flooding entirely by stopping block physics.

Check here for a description of all of them. Also, I forgot that you have to include Server. before the VERSION_0020 in my hypothetical plugin. like if (p.ProtocolVersion != Server.VERSION_0020)

You're right, I forgot that the client actually sends different protocol versions. I was thinking about how classic versions didn't send an AppName, but that's not needed to tell the difference in this case. So basically it is possible, with a simple plugin. You can copy the KickNoCC plugin and modify it so that instead of checking p.appName, it can check if (p.ProtocolVersion != Server.VERSION_0020) then p.Leave and set p.cancellogin to true

Unless 20-23a implements unique network behavior compared to other versions, this is impossible

It would help if you told us where you got this plugin from.

Looks like you should probably just use UnknownShadow200's solution then, WoM sounds a bit too much of a hassle for you. If you really wanted to try WoM though I'd recommend trying to install java if you haven't already, or if you have, get java 6 specifically

Could you have given a less helpful response? lol Did you download WoM from the link I provided? If so, can you provide a picture of the menu it brings up?

No account is required if joining your own local server. Enter any username you wish then enter the port and hit "Go"

Join the level, with WoM client, then dump the level with the button on the top left. It will appear as a .dat in the WoM directory.

MCGalaxy is multiplayer servers. You cannot make doors in singleplayer.

There are no doors in singleplayer. /door only works in MCGalaxy (or MCLawl-based) servers.

Aha, you got an error? that means something went wrong.

They are using Not Awesome Survival or a modified plugin based on it.

It's based on the free version that used to be available as a java applet at https://web.archive.org/web/20130928045438/http://minecraft.net/classic/list. This version was 0.30 set to "creative" mode, which had survival features disabled and infinite blocks. It's called c0.30-c in the Betacraft launcher.

Try doing basic things like reading and browsing the site after logging in

Surely you can provide mode details than this

This person (usually known as "Pockie") is an old player and she was pretty much just trolling here. I also recommend a mute

it is simply tomfoolery

You're correct, you need to make or find a skin for the pony model for it to work correctly. Here is a template and a higher resolution labelled parts template. You can visit "ponyskins" map (/goto ponyskins) in Not Awesome 2 for more skin examples/templates.
