tagging

I have had a delicious account for some time and find it useful when using computers away from home.
I have found this 2.0 unit very interesting and useful. Actually hoping to use more of this technology in promoting and interacting with Grant County Library patrons.
Also created a google doc yesterday and sent it to my kids to work with - my one daughter admitted she liked this better than attachments. However, it is another account to remember.
How does everyone keep track of all their user name and pass words???
Thanks for listening.
