It makes me think we should make a little tutorial on how to use Qt Linguist to translate
quests the quest editor, so everyone could translate it and not only developers

And if you're good at web development, your help is welcome for helping me on the website. I was thinking about creating a free and open-source Wordpress theme not only for Solarus, but that could be use for any software project, since categories are always the same (dev blog, download, FAQ, dev documentation...) . I noticed such theme does not exists for the moment (or is not free). So your help is welcome there too !
