Hi all. Please take note of the following updates and announcements.
- All the tutorials in the GeoGebra Essentials Series are now updated to GeoGebra 4.0. I am working on the other tutorials as well.
- For those who want to add me up in Google+, please see the side bar or use firstname.lastname@example.org . You may also want to add me up on on Linkedin.
- If you do not want your emails to be flooded with posts (I usually make one post a day), you may follow me on Facebook, Twitter, or Friend Feed. Of course, you are welcome to subscribe to my RSS feeds.
- If you want to contact me, please do not use the comment form. I am receiving at least a hundred spam comments a day, so I might not see some comments. If it’s important, please email me at email@example.com.
