With the addition of the search box, I've reorganized the other links in the header. As a consequence the links to your profile, your account settings and the sign out link have been moved to a sub-menu, which is accessible by clicking on the "member" icon. The username is only shown on the desktop version.
Could you please confirm that you have access to this menu?
Do you think that having your username on top of the page is something important for you?
The pace this website is now changing at is great. Especially after such a stagnant period we're starting to leave other communities in the dust it's just a shame the forums aren't attracting more people.
