this is extension am searching for.I have done a technical fest site for our college event and i hav to put a Thank Note while the site loads after the completion of the event.this worked like anything.only problem i had was it is showing a blank box in the module position in which i hav displayed it..everything else is fine for me.thanks for the extension.

This is the best popup HTML module for joomla. I needed this module to put a floatable TV screen on top of Chatroom. It works like a charm. Check it out on www.Lakay.tv and click on Chat to see it in action.
