I was at the library and logged into my LinkedIn Profile. Someone closed by browser and I went back to my public profile and clicked sign in. I was surprised it went straight to my edit profile without asking me to sign in!
Hmmm, not nice. I will check with the LinkedIn people and try to post some kind of solution here.
In the mean time I did this. I clicked Tools, delete browser history, and then deleted cookies and passwords. I closed the browser, went back in, and it "forgot" my password and asked it form me again.
Jeez, be vigilant at public terminals.
