I guess this out of purpose of this hack, but this can be done using simple JavaScript or AJAX of course. Depends on functionality you need.

I have it done with simple Javascript I'm just wondering if I can add the ajax this script uses to look "pretty" ;)

amazing great mod

Very nice, i remember there was an older one for 3.6.x. I hope this one will look as good as the beta 4.0 version of it. I remember it would divide the process into multiple steps to help users. First username then password so on..

Instead of defaulting the weakest password to images/rating/rating_0.gif, you should make the lowest one images/rating/rating_1.gif because rating_0.gif is an empty space.

Also change Password quality to Password strength.

Yeah i agree or have that power bar system the old mod used. May i also recommend using a green tick symbol for correct entries. This mod has allot of potential but needs some tweeking.

Installed using default VB skin and was not able to get the password strength images to appear.

Tested with a very complex password, and images show.

I would agree with some sort of Check Mark for a good Username/Password

Looks great! Still more work to do, though IMO. A tick would be good for a "good" username, although that can be easily added.

Also, when entering a password, only one star shows for a 4/5 star....but near the end :S

Does this check our vbulletin option for "username regular expression" while validating the username?
