Yes, this is important. Recently, there have been links leading to an 'Optifine Website' that is apparently a giveaway for its 3rd Anniversary. Mind that this is fake! It is completely fake and do not enter your E-Mails and Password into it. To give you a brief look at the fake, here it is: http://optifine.support/CapeGiveaway/ As you can see, this is the real website: http://optifine.net/home.php Here are a couple of questions you should ask yourselves before doing anything: 1. Why are the 2 links different? 1 has optifine.support but the other has optifine.net. 2. How come the end isn't this: http://optifine.net/capegiveaway 3. Why isn't this announced across the Twitter, etc? Now let's spot a difference: 1. The fake giveaway background is plain white while the real Optifine website has a snow white background. The thing is, you can type ANYTHING in those 2 slots and still be able to get in. The part after says that if you share it with 3 friends, you get an Optifine Cape. It's trying to get more accounts hacked. This is a simple warning for those who do not know yet. If you have completed this properly, change your password immediately.
