This is a really good example that shows us how to create a password strength meter with a beautiful Ext User Interface. It uses the algorithm based on the code of Javascript Password Strength Meter from Geek(Wisdom).com and then use the Ext Forms to build and layout forms on the fly. It looks stunning and really professional, however this Ext form do not do anything and have very little validation on the other fields except the password field.
