What permission Plugin is up-to-date and works and is good right now? Like what can I use and then change someone's rank in the Nether World and Main World to Member, donor, or something using a command. Also, would it be the same set up as the old Permissions Plugin? Like how it is, "- "permissionnode.node*" or something. Then how the ranks are set up and all that?
I use permissionsbukkit with superpermsbridge. http://dev.bukkit.org/server-mods/permbukkit/. It seems to work fine with 1.8.1 There are in-game commands and you can change the permissions on a per world basis. Yes the config is very similar it just adds true or false to the end and no dash example... permissionnode.node.*: true It doesn't use ranks as far as I know.
Yes you can set up group names like you list. I misunderstood...there were ranks in the old permission plugin (never really understood them)
