Today I changed the language settings of my Team Web Access account for Team Foundation Server 2013 and here is how to do it for the ones looking for this info.
1- Open Team Web Access
2- Click your Name on the top-right corner
3- Click “My profile”
4- Click “LOCALE” tab on the window that opens
5- Change the “Language” under “SETTINGS”
6- Click “Save changes”
Hope this helps.
Good Luck,
Serdar
