I'm not putting anything with only 37 downloads on my computer. Without going through the source code myself I can't be sure it won't mess up horribly, and I'm not going to do that.
Are you considering adding things like NPCs such as Shop owners? I mean the Market is basically useless right now.
No, not really. And the market is mostly for show, so I wouldn't say it's useless.
There are other neat mods that I would like to have on the server. I don't like the idea of having any more dimensions or a ton of new items, but there are a few things that I think would enhance the experience. Just let me know if you're even open to the idea and I'll test them out tomorrow night.
To be honest, I'm not really interested in modding the server at all. It's a vanilla server, and aside from some very unobtrusive plugins, I'm not really considering changing that. Plugins and mods have a way of overwhelming players.
