Besides
tungfa's comments, which I agree with, I want to add a couple thoughts (not going into the rebranding discussion, this is not the thread and it has been discussed already many times) that are not exactly related with branding but are with calling things official:
"Official" should be handled with extreme care. Official is something from darkcoin.io, @darkcoinorg or the Official Development News and Information forum. This is important because we are distributing software that deals with money. There are already malware darkcoin clients that will steal your coins or someone could publish an ill intended guide that exposes your funds. Official is safe. Unofficial is probably safe too, but the darkcoin project can't guarantee and you should do your due diligence. This doesn't mean that people outside the team are not honest, they could have been hacked or made a mistake. I'm part of the team, but if I personally start something related with Darkcoin it would not be official, it would be mine.
Also, some of us are putting our names out there and affiliating ourselves with the project. I have no fears about it because I've joined a project with a very specific view that I share, but if some people start to do/promote certain things and call that official, that could bring trouble to us personally.
