Sorry I can't think of a better title - but if I click my Username (Welcome, Zenerdiode) in the top right; the website just times out. I use this link to get to the page where I may see my own threads etc. I've experienced it at Work (Win 7, IE11 through corporate firewalls) and at home (Win 7, Firefox and OSX Safari).

Is it something you are able to recreate?
