THIS IS A MEMBERHEIST WALKTHROUGH! SPOILERS...
Follow this link http://macheist.com/forums/viewtopic.php?pid=55229.
Notice anything about the first post? Yes! The bolded letters. Write these down in order. Now, open the first link under Top Secret information. You will get a page with a text entry box requesting a password. What do you think the password could be? Yes! The bolded letters you wrote down. Enter those now. Now you have two text entry boxes: One big, on small.
Now, go back to the link you were at and click the second link under Top Secret Information. This should bring up a guy's blog called 400. If you remember, the page with two boxes requested the thief's name for the smaller box. Go to the guy's blog and search for his name. It is the very bottom post and you will find it when you click Read More. His name is Robert Jones. Go back to the page with two boxes and enter Robert Jones for the Thief's name. Now for the bigger box...
This will take most people a while but just click Submit without entering anything into the bigger box. Now...OH NO! LOCKDOWN/SHUTDOWN!!! This is just to throw you off. What you really need is the bunch of letters and numbers below the shutdown, lockdown message. Copy these letters. What do you think we do with them? Yes! Press Back on your browser and enter that in the bigger box Tah Dah!.
A special thanks to mwgwalker! You helped me through the whole heist! Good on ya!
