One hour till 2019 and I brutally overestimated the time I have to spend uploading; I'm basically done!
This means that I'll soon be able to move this whole thing to the main site, instead of having it on a subdomain (i.e. it'll be on [dschirsaanjo.hu] instead of something.dschorsaanjo.hu).
All I got to do is to write the home's multilingual intro texts, enhance the already written short texts for pages, and write my about page. This latter is a tough one, meaning it should not only be sensable and rather lengthy, but also written in 3 languages. And, of course, somewhere I got to meantion where to access my other things where I publish/archive. At least everything that left is done on the site and I won't need to access the servers directly, fiddleing with CSS, PHP and whatnot.
