Alright, I've looked around this forum for ages but can't seem to find an answer to this question:

How do you tab chords so that when your mouse hovers over them the small pop-up appears showing the chord diagram?

I tried copying and pasting some javascript from other users tabs but that didn't seem to work... All help is greatly appreciated.
Just select "chords" as type of your tab in 'submit your tab' page and chords will be highlighted when your tab got accepted.

There's no need for java or anything else.

emad I'm gonna ban you, seriously.
Alright, that's cool.

Also, how do you differentiate between an open G or a G barre chord?
