Great person! Resembles the ubuntu spirit and follows the Ubuntu Code of Conduct. We have worked together when the ubuntu-gr forum team decided to apply the new "ubuntu lucid" style. He has not only fixed numerous bugs, but also solved a number of cases where users requested help. One of his most prised gems is troubleshooting.ubuntu-gr.org, which is a helpful tool for new users to troubleshoot their problem and figure out a solution. This tool also accepts easy addition of question-answer pairs -- people with none or minor coding background have contributed. Savvas Radevic

Dimitrios has dedicated a lot of his time promoting Ubuntu in Greece, providing support to new users, improving our forum infrastructure, translating free software, .... . A very worth mentioned contribution of him is that he collected and documented all bits and pieces that are necessary for having Greek OCR support in Ubuntu. This contribution removed a barrier for many users in Greece to migrate from windows to Ubuntu. logari81

It is difficult for me to count how many times Dimitrios helped me with issues I have had with ubuntu and many open source applications at my laptop and netbook, as he is offering his help and knowledge every day at the greek comunity of ubuntu. I deeply respect people like Dimitrios, who help simple users like me to understand and learn about ubuntu and open source software generally, because if they were not there, there is a strong possibility that me and many of us would still be using windows. Dimitrios did a great job before he became an administrator at ubuntu.gr forum, and in my opinion since then he multiplied his efforts. Dimitrios thanks again and keep up with the good work. Th P

Beeing a relatively new member at the Greek ubuntu community (Ubuntu-gr) i admit that i am ipmressed by the amount of personal time and effort a volunteer like Dimitrios Ntoulas (mainly known to me by his nickname as the administrator of the Ubuntu-gr forun) commits just for the joy of helping new members. I must say that i find this very inspiring and motivates me and a lot of others to follow this example and promote the idea of the Greek ubuntu community.Fkol k4
