Well... I was playing Skyrim a lot. So Fus Ro Dah. And I also like orpheusFTW's "Misadventure of Skooks" youtube videos. Sooo, Fus and "Swooce" rhyme. So I picked my name - SwooceRoDah!
That still wouldn't be very secure, because the person could just use a different wi-fi signal (like free wi-fi from McDonald's for example) to boost their diamonds. Or run their IP through a proxy to scramble it. So it's not very secure.
To get back on topic - perhaps this feature could be used for skins. When hovering over a skin with your mouse, a drop-down menu of sorts could display the skin in it's 3D preview form. In the corner, there could be the diamond icon that also displays how many diamonds the skin already has received.
Non-PMC members diamonding would not work. Because then, the person diamonding would be able to just refresh and diamond again, and that wouldn't be very good :/
Upload skins, projects, texture packs, and blogs to gain XP! The more views, diamonds, and downloads you get will increase the amount of experience points you get.
Build the most powerful PC known to mankind. Then use some money to get good experience in coding with several different languages. Theeen use some more to get a job at Bethesda Softworks, the rest I would save
I sure would like hats for both servers and single player without any kind of mod. Hopefully they would be customizable. I know it doesn't sound like much, (and would be moderately difficult to program) but I would still want to have hats xD
Princess Mononoke was pretty awesome too. But yeah, a tad bit mature. Still, just about every Studio Ghibli movie is worth watching. And for another quick one season anime, I recommend My Bride is a Mermaid. It's on Netflix
Well all I can suggest is completely uninstalling Minecraft and downloading it again from the official website. If that doesn't work, then it is something wrong with your Mac.
