Narendra Rocherolle asked me to convert the Google Calendar widget into a 30boxes capable widget. No problem, it only took like 10 minutes.
So if you use 30boxes and want a nice and simple WordPress Widget for displaying events on your calendar, well, here you go: 30boxes Widget
This is, of course, a first stab at it only. I can and probably will add more functionality to it (like start and end dates). But that can wait until later. Right now I need BBQ!
