I set up wpyogi.com years ago after setting up a WordPress course.It took me so long to prepare that material, that I decided to put it up online for students to use on their own and for teachers to use in their class room. I no longer teach and as a result the material now needs updating. A few weeks ago I reached on on twitter to see if anyone would be willing to take over the domain and Syed at WPbeginner kindly agreed. Not only did he take the domain name, but also took the content with the aim of updating it soon.
I look forward to seeing how the content evolves.
