Its working but , low smiles db , but we can add some smiles to this and if the scrip can resize chat box it was better ;)
I mostly use the pop out version of Facebook chat. I very rarely use the docked version. Can this also be added to the pop-out version? Chat > Options > Pop out chat
well, recently, i keep trying to use it. but it didn't work.. maybe it needs some update.. but i found a better one.. http://userscripts.org/scripts/show/50826
it has bold and underline feature..
So maybe you need to update this script..
thanks Giuseppe Maria
