ummmmm, why don't you use the same password for all of them? or some simple variation of the main one. Additionally, use Firefox if you aren't, it stores the passwords better than Explorer
I mainly used the same 2 or 3 for everything until my last job. They put special conditions on passwords to enter their web sites so I just put the web site and a password hint in a spreadsheet and password protected it.
Just remember 3 passwords and then make a list of all accounts you have and place an A, B, or C next to them.
A. for less secure info (hotornot, classmates)
B. for secure info (yahoo)
C. for very sensitive info (banks, CC, books)
