November 2011
The latest new feature added is WORLD RANKING. You can view your current world ranking (and country ranking) by clicking on the world ranking icon on the right sidebar. My hope is that this feature will make people want to rank high in their own country. It seems to be working. Students are averaging over 35 completed units per day!
I haven't had a lot of time to work on the site lately ;( I've been busy at work and helping my wife take care of our daughter. I have a newfound respect for parents. Being a parent is much harder and more time-consuming than I ever could have imaged.
If you want to see the site develop faster, and you think you can help, please see the partners page.
As always, please give feedback and continue to recommend English 4 IT to your students and friends.
And most importantly... HAVE FUN learning english and IT,
