After making a number of edits to wikipedia, it is time to make a more permanent account.
Why the username "Ubuntu user"? Well, Ubuntu (Linux distribution) is the operating system I use. I started using Ubuntu after I prepared some computers for use in Africa and I learnt that it is more efficient than Microsoft Windows: it is faster, it is free from viruses and spyware, it is compatible with more mediaformats including the OpenDocument standard and it is free.
