 I got involved into open source for more than 20 years since my freshman year. At first I just used that pre-desktop and then from about 1999, my first job, and I started to contribute to open source. Mainly for translations, sometimes a bit cold. I can call, I can call, but I seldom can't be called in. So we started to contribute and I joined a project about migrating free software into schools. And of course for open suite, we always introduce open office at the time. For LibreOffice, it's about since 2014 or 15, our government starts to push the policy using ODF as a national standard format. And we as open source promoters, we think it's a very good chance and a very good policy. But I know, we know that of course the government, one is they will face a lot of resistance. And the second is that they may do it in a not so correct way. So we have a chance, so we start to cooperate with our national developer council. That's the first level you need in the central government. So I get involved into LibreOffice more before we just tell people to use that. But then I got involved, I helped Iran County and I helped NDC to start to, mainly to communicate with people because we know some key failure factors. For example, people don't understand this. People don't understand why open source, open standard is better. And we have many experience talking with those people. For example, in school teachers and students and other people that they have no idea about open source. But we have many experience with that. So we get a chance and we start to help and need to hold many big explanation sessions about telling people why we need to use ODF, what's the advantage of that. And what the problem we may face, but what attitude we should have. So I think our communication is worse. So people are starting to accept and more and more, I present today, more and more files are generated by LibreOffice. Sometimes open office, but most are LibreOffice. When advocate LibreOffice, actually what we tell people is that use the correct way to generate documents. And LibreOffice is one of your two worst choices. We don't tell people that you should use the LibreOffice, no. We just tell them that first you need to have the correct concept how to generate, how to type setting of documents. Sometimes for this you need to use topic. You need to use heading one, but usually people may just center the text and the large, the phone size larger. But I will tell them that using the correct way, even if you are using Microsoft Office and we got a DOC as well, that would be better. Because Office Suite or we say World Processing, so where they will treat these things, usually if you use the correct way, they will treat things the same way. So the conversation problem will be a lot less. So our training course, our communication phase, usually I will focus this concept to people that you have the correct concept and then you have many tools to choose. And use under the open standard, under one standard. Now this standard, our nation, we select ODF standard. So under the standard, using the correct way, you have many tools to choose. And this year, last year and this year I attend the ODF process. And that made us understand, okay, this software when processing ODF, what problem it may raise. And this year even better because Microsoft finally, they have to be attending so I show them every problem we met to them and they understand our problem. So we can tell people that no, we are using ODF, we are not against commercial or proprietary software, they are all chose for you. But of course the software needs to follow the standard correctly. Yeah, so under the circumstance, so you have many, many choices. And for now, LiboOffice and our own NDC application tool, that's the tool I bring this year to test, they are better choice for now. And of course we hope that Microsoft can improve the processing for ODF and then people have more choice, not only Microsoft, but even this year in Academy I also talk about Caligula. Yeah, I also talk about what we need in Caligula. I hope people can have more choice. So that's the way we advocate about LiboOffice or ODF. Of course LiboOffice has already been good enough. And of course they have many things to improve. To me it's how we can make more people understand that LiboOffice is a free software, it's a very good office suite. And the most important is that everyone can together make it better. In any way, reporting a bug, writing a document, everyone can make it better. And I think we need to make more people understand. And maybe design several shops or several ways, easier for people, especially those who have no experience about open source, they may not know how open source community works, but at least following this in a workshop they can do contribution. And of course we can highlight the contribution. But I think what LiboOffice needs is to make more and more people understand this. Everyone can make it better. It's free software.
