The list is updated whenever an editor comes out. If an editor hasn't been made, it won't be added to the list. It should be noted that this is as close to a complete list as pureIso can handle, but there is always a chance that he hasn't heard about an editor. So if you find an editor on 360 Haven that isn't listed here, post a link to it in this thread.
Like so. Which leads me to the issue here. Normally we don't talk about bans, but Ryder Lute is a public case as it is, so...
Without going into too much detail, he was banned for stealing content (source code, research, etc), and in response, he made all the downloads to his tools password protected so that we couldn't access them. Which is alright with us, as we've been spreading the word around Haven to avoid his tools anyway because "his" tools are usually stolen source from somebody else's tools, as well as because better tools usually exist. In this case, Idle's editor, which is top-notch and relatively stable (as well as original and not stolen).
