Who we are and why we’re doing it
Our organization, Edukado@Interreto (E@I), has long had an idea of organizing a language festival in Slovakia. We’ve been working on the topic of education by means of internet since the beginning (2005), concerning language learning mostly. We create various free multilingual websites. Our activities began by creating the first ever multilingual website for learning the international language Esperanto: lernu.net. Esperanto bears a great significance for us (it’s even the working language in our international office), but we’re busy with other languages, too. We’ve been gradually adding further new projects and languages: slovake.eu, deutsch.info, lingvo.info, russky.info, polski.info etc. Here you cane find an overview of our projects. Besides creating educational websites, we organize various events as well: trainings, seminars, workshops, conventions, summer schools. We’ve been focusing on languages since the organization came to life, and we’ve already noticed the absence of this kind of event in Slovakia. Thus we thought to change this, and now we’re extremely happy to have found like-minded people with whom now we can prepare the event for you!
The vision of E@I is a world of peace and harmony. In which all its citizens are able to quickly and easily communicate with one another all over the globe. The main aims in this direction are:
- to encourage intercultural education, collaboration and communication;
- to support learning and using of internet technologies and languages;
- to help realize the Charter of the United Nations and The Universal Declaration of Human Rights (UDHR).
In order to achieve these aims E@I initiates and supports projects involving international youth cooperation, organizes educational and cultural activities related to the very aims of the organization and promotes the importance and necessity of international communication with no restrictions.
Volunteers
LingvaFest is an event full of a rich, language-focused programme: informative lectures, interesting workshops, fun crash courses, colourful concerts and an excellent accompanying programme. All this is made possible not only thanks to the organisers, but also thanks to the excellent volunteers who help us with the event. To all of them we owe our thanks!
The volunteers are ordinary people, but they have decided to give a little extra of their time (and skills) to this event. They are very important, even though they may be doing work that the average visitor may not even notice – all the more necessary as there is a lot of this (and other) work around an event like this. What does volunteering at LingvaFest entail? There are more than enough tasks, everyone can choose their own (and if you’re not sure, we’ll happily find something for you): working at the info booth, checking and managing technical equipment, providing refreshments for speakers, setting up the presentation rooms, carrying things, preparing materials for visitors, and more.
You can help by volunteering even before the event by contacting exhibitors, getting sponsors, approaching speakers, writing articles, and press releases, etc.
Would you also like to experience LingvaFest from a different (more adventurous) angle than just a regular visitor – as a volunteer? Then fill in this form and become an active part of the festival!
