I would like to know why there is no page about delta-chat on Wikipedia. For example, in this wikipedia page, there are various types of customer email, but there is no comparison with delta-chat: https://en.wikipedia.org/wiki/Email_client
“we”, so the “Delta Chat Developers”, would appreciate an entry in the English Wikipedia very much.
however, after first experiences with the German Wikipedia, if one is not used to Wikipedia internals, this is a very time- and discussion-intensive thing.
so, in favour of other things, no one from the core team pushes the English Wikipedia forward - also, in general, it seems better and more neutral, if the article is not written by the creators.
but if the approach comes from the community, from people familiar with Wikipedia internals, this is another thing - see the German Wikipedia article - thanks @webratte and others.
so, if someone thinks that there is missing something, and maybe even has some experience with Wikipedia, go for it same for other languages.
