Diigolet uses cookie to mark the user's state, so that users can use diigolet until they sign out. So, if diigolet do not use cookie to mark any more, the user's state will be clear after use close the browser and need to sign in every time when they save bookmark. I think that's worse than now.
hi, did you see the edit menu when you put your mouse over the highlight? can you find the "delete" item on the popup menu? and what's your browser, IE, ff or other? thanks
