ahh, OK. I have just added the API module a few days ago. I shall check it out. So far, I have not used it directly, it is just required by other modules.

I also noticed, that it takes a while to refresh, and display new status, even if you click reload/refresh in ur browser. It aint really a great deal, but it is slightly annoying.

BTW, I have copied your site. I have deisgned my own version of JS random text display. I coded it all in an external JS, and then called it from da Block.

There aren't any security

There aren't any security issues here. What you have to worry about is input from outside, everything here is internal to your script.

Couple of side notes (not really what was asked for, but hey-ho)
Are you adding this to a block in Drupal? You should really use the Drupal API if that's the case, although as the chat stuff is in a different database it might not be worth the bother. Also, <b> tags are evil, presentation belongs in the CSS you see, in place of <b> you should use <strong>.
