The move was made for technical and practical reasons. Visit https://learn2c.org for updates made through out 2017 and into 2018.
However, things have changed since then and as of the spring of 2018, this web site may return to here. If that happens, the plan is for the new learn2c.org address to point here as well.
Many of the technical issues that caused to migrate a year ago have gone away or been solved.
The learn2c.org web site is hosted at WordPress.com and it appears Google down ranks WordPress web sites in search results. This old appinventor.pevest.com site – even without having been updated in a year, continues to receive many times more visits as a result of searches than does the WordPress.com hosted web site!
Finally, WordPress raised their hosting price last year.
