Well finally got a calendar that can be used with infopop. If you go to the main page of the forum (http://expattalk.com/ or click on the Expat logo in the header) you can see it. The dates with something in them are green. So the first item I entered is for the 20th of this month when ICI is due.

If you would like to be able to add items to the calendar, either, post a message in the Calendar forum with the info and I will enter it or send me an email or Private Message and make sure you include your user name then I can give you permissions to add it yourself.
