I have two niggles with the shoutbox on the other site that may be fixable:

1) The shoutbox is quite small so it only shows two or three messages. This is an issue when trying to follow the conversation as you have to do lots of scrolling around. It would be nice if there was a little button that would make the shoutbox full screen in a new window, a bit like a forum thread then.

2) When scrolling down the ST-RS page using a trackerpad or mouse wheel, every time the cursor goes over the shoutbox it starts scrolling that instead. This is made frustrating by the shoutbox spanning the whole width of the ST-RS page so the cursor can't possibly miss the shoutbox.
