Those impossible to remember passwords are real pain!
The system is designed to issue you a password when you first join,( I didn't design the system, it comes like this)
If you can't remember or have lost your system issued password, use the facility to get another password.
Once you are logged in using the password issued automatically by the system , you will see on the top right hand side of the page (The right hand column) "My Profile Summary"
In that menu see "Edit my profile" Click on "Edit my profile"
In the dialogue box that opens you will see, at the bottom of that box, the option to change your password to one of your own specification.
I am sure members will find this helpful.
