Finally, I am back, my laptop is alive and I published again my wordpress plugin: iCal4WP. I took this opportunity to fix a bug thanks to Roger (sorry I could not get the widget code yet). I plan to be back on the development soon to release a new version before Christmas.
Finally I put my own plugin on this blog as a demo (at least you can see the client side of it) and I start to use Flyspray to follow-up bugs and feature request, you can access it at http://www.innovativemap.com/flyspray/.
