To all the folks above suggesting to make issues for TODOs, I absolutely agree. It would be wonderful to have that in place. The fact of reality is this is a hobby project and I dedicate almost 100% of my free time and lunch breaks to work to make Sponge better.
@blood and myself have spent the better of the last few weeks ensuring that the World creation/management API is as stable as can be. Its almost there; a jarring bug is on Sponge’s issue tracker that needs to be resolved (I’ll fix it or he will sometime this weekend) and we still need to make gamemode switching working between worlds.
I can’t do it all myself nor can my team. I’m pushing my people harder than I ever did my previous team in Spout and its a wonder that I haven’t had a mutiny on my hands. Its simple to make a forum post; its much harder to get out there and contribute.
To put it simply, we always need code, docs, feedback, anything really. Get out there and make a difference: help us out :).
