Very soon del.icio.us will be releasing their new interface and making the transition from http://del.icio.us to http://delicious.com. When that switch occurs you will automatically be logged out of your delicious account. With that in mind it is very important that you know your delicious username and password. Read the following blog post for more information from delicious on the transition.

Another change you will see is your delicious website address will also change from http://del.icio.us/username to http://delicious.com/username. At this point it is not clear if your current address will function or not. To be safe you should get into practice of typing your address using the new convention. It has been verified that your current address will resolve to the new one. It is a good idea, though, to get used to typing the new address and plan to give to your students, colleagues and friends. See the comments for an explanation from delicious themselves.
