I have been watching discussions about the coming EULA changes and have decided that I am not going to make any changes to the shop or donation system for now. This means all ranks and packs will be sold as normal until further notice.
I have been following some discussions between other server owners and it is generally believed that we can continue selling ranks/items as we have been doing and that Mojang won't/can't enforce the EULA any more than they have been.
That being said, I do have a plan in place in case we do have to change the way our shop works in the future, and no one that donates will ever lose their ranks or items.
Again, there will be no changes to our shop or donation system at the present time.
