Joomla 3.0.0 was released on 27 September 2012. It was even easier to install than previous versions on the local workstation, using the Wampserver bundle from http://wampserver.com/en. I installed it on my remote server using the installation tool of the hosting provider. Everything went well. I installed reCAPTCHA and read the story about it at http://www.google.com/recaptcha. Taking part in the effort to OCR books is a contribution to the science, similar to the screensaver I was using several PC generations ago when it ran the SETI application. Berkeley University is still running that program.
Then I wanted to see if Joomla 2.5 templates would work on 3.0 and installed one. Big mistake - fatal errors happened both at the front end and the back end. Back to LTS version 2.5.7.
