TL:DR - I'm shutting down Colonialcraft
I'm just going to go ahead and do what I almost did around Easter, which is shut Colonialcraft down. There is basically nobody left who was part of the original server and premise, and I simply don't trust anyone left now to do the server justice.
I saw the early ideas regarding roshi's project, and I can safely say it isn't Colonialcraft. If something is brought to fruition, then I'm afraid it will have to be hosted under a new website and I recommend starting afresh under a new identity altogether. If he decides to "keep" the name Colonialcraft then I can't exactly stop him, however as the current "owner" I won't recognise it as such so any future servers acting under the name of Colonialcraft will be unofficial. The original Colonialcraft dies here.
If you want a more indepth explanation on why I'm shutting the place down as opposed to transferring ownership or other alternatives, then I'll probably go in a bit more depth in the comments/chatbox if you ask. The plans for the website are to basically let the "premium" version run out in less than a month, I'll probably put the website offline a few months afterwards.
In the meantime, good luck for future endeavours, it's been a good 3 years.
