Re: HTML
It depends on where you want it to display. The easiest way — and what seems like a good place to display it — is probably to make a module for it. Go to the Admin Modules page (tiki-admin_modules.php) and scroll to the page bottom. "Name" is the module name which, judging by the default modules, shouldn't have spaces. "Title" is what actually appears on the page, maybe "Online Status" or whatever. Paste the HTML into the Data area and click Save. Then assign the module to a prominent position in one of the columns, on the Admin Modules page.
