Integrating username into yshout shoutbox

[apinner]

Hi,

I am currently trying to integrate the yshout shoutbox into an existing forum. Its easy enough getting the shoutbox to display using an iframe but the 'Nickname' box on the shoutbox is just a text field that anyone can fill in with anything. This obviously causes problems with moderation etc as people can chat using any name.

I am trying to replace that field with the users forum username ie $bbuserinfo[username] but the shoutbox is hosted on a different domain/server to the rest of the forum. Is there a way to extract the users forum username from VB to be used in an external php script.

I have searched around and found very vague answers. Any help is always much appreciated.
