mathe.ellak.gr is an campaign to promote free and open-source software to the Greek-speaking audience.
The purpose of the campaign is to provide a short and concise message to the visitors; and also helps to direct people to the website when they show interest about FLOSS.
It comes with logos of different sizes that you can put on your website so that you can direct your visitors to the campaign.
Got to put on on the Greek planet, planet.ellak.gr. 😉
