--presentations will be recived in English and Czech or just in English. We would like to find and interpreter, who would be able to translate to English
The Dutch conference last year had an English 'track' - in parallel to several sessions in Dutch. This seemed to work well in appealing to both Dutch and international attendees.
* Will there be any funding available for travelling costs?
--Well, I dont think so, that Wikimedia Czech Republic will be able to support this. We will offers some travel and accomodation help.
So, to clarify, are you indicating that there will be no financial support, but that you will offer other help, such as advice..?
When there's a bit more info, I'd encourage you to advertise this more widely within the Wikimedia community than this list. The Dutch chapter organised a conference on 'Wikimedia and education' last year - they might be able to give you some tips. Also, let me know if I can help in any way...
--well, we know how to say to different language groups, via their Wikimiedias or mailing lists, but how to inoform differennt English folks?
Oh, I just meant through lists like Foundation-l, and perhaps Textbook-l. There are also any number of lists and communities outside Wikimedia - it's common for organisers to post to a few, and to invite people on those lists to forward the CfP to lists that they themselves know - academic 'viral marketing' ;-).
