You may be thinking about... http://hp50g.pbworks.com/ The password used to be something like hp50g or hp50 or 50g. But that may not work anymore. I suggest you create an account (whether you plan on creating a wiki or not) and use your created username/password to sign in to hp50g.pbworks.com Hope that helps.
