Like everyone else, I was having trouble linking my email address with my Bungie account. After a couple of hours, I think I have a solution because it worked for me and I now have my email address linked. The email address I was trying to link is a Gmail address which is the address I use for my XBL gamertag. After hours of logging in, logging out, restarting browser, etc. I was still having trouble. However, I realized that my xbox was on and I was signed into my gamertag- which means I was signed into the email address that is associated with my gamertag. I turned off my xbox and I was instantly able to successfully link that email address with my Bungie Account. Whichever the account/email address you are trying to link to your Bungie account, Make sure you are logged out of EVERYTHING you think or know might be logged in else where. This includes the following (I did it and was instantly able to link my email address): youtube.com facebook.com twitter.com xboxlive.com Itunes (Apple I.D.) Netflix.com and anything else you can think of that might be using your specific email address. Also make sure you are logged out on other devices or turn other devices off including: Iphone Ipad Ipod Cell Phone Tablets Xbox/Xbox 360 PS3 Smart TV's It sounds like a hassle, but I did it and I was immediately successful in linking my email address to my Bungie account. Remember, you always have to have some sort of account/email address linked with Bungie Account. So if you want to link another account/email address you will probably have to do a little bit of logging in/logging out until you are able to link the specified account/email address. Let me know if you have any questions and I'll do my best to help. Also after logging everything out, and re-opening your Internet Browser, trying using the "Private Browsing" option before continuing to Bungie.net page.
