Linux is a free and open-source Unix-like operating system typically packaged in a form known as a Linux distro (distribution) for both desktop and server use. Some of the most popular and mainstream Linux distros are Arch Linux, CentOS, Debian, Fedora, Gentoo, Mint, Mageia, openSUSE and Ubuntu. The Android OS is Linux kernel-based and used by many smartphones and tablets, as is the Chromebook. We are very experienced with Linux and use it daily on all of our servers.
This was a Joomla membership site using Community Builder, CB Subs, Jdownloads and Virtuemart providing online courses. It needed everything updating, including Joomla migration from version 1.5 to 2.5, a replacement template, the payment gateway, and content access rights restoring.
They know Joomla! and CB subs very well indeed and I would definately recommend them. Based in the UK so I had none of the usual communication problems that I had with previous developers. Very responsive (I have tried lots of developers previously who have not been able to manage their workload as Andrew seems able to do).
