trting to access Q&A is difficult. Big square to right links to classified. I can only find this by 3 menu bar link on top of page. Then I must sign in every tome, and go through the search process to Q A again. I am never recognized when I return.
I fixed the incorrect links on the Home page, but you can also get there through the menu as you mentioned and the notifications on the upper right if it shows new Q&A activity. Whether you stay signed in depends on your browser/device settings and cookies. Works fine on Chrome, Firefox, and Safari on my computer. On my iPhone it forces signing in more often, but saves my credentials.
