The /home replacement is only difficult in that I need to convert all the homes over. I’m not excited about storing all that data, but it looks like CMDBook stores even more than I would.
RE:MCMA, I’m currently only using a few features in it — console, start/stop/restart, schedule. It does make certain things more convenient because it’s a wrapper.
I wouldn’t use a plugin for cities. I want to scale it up slowly, but the important component right now is the warps. Maybe I could get rid of /spawn at some point, too.
