Visubox

I hate to be the one to bring foreign apps to this forum - if it is not allowed, please let me know if you delete it.

Here is my question:

I have the Visubox on my site at www.kistech.com (it is in the 'Shout Box' module in the column on the left side of the page).

I am trying to figure out how to make it so that instead of using nick: 4568 as a name, it uses the names of the people logged into the forum instead.

Does anyone have any ideas?
