I have changed the page to English and saved the German version elsewhere; wasn't much effort anyway. This article has been activated for tanslation meanwhile so that's my project for today.
As none of your links provides what I wished for as a beginners page (a general OpenPGP page not bound to certain software) and I didn't know any such page, not even in German (embarrassingly: including my own) I wrote one myself (which is already linked in this article).
Ideally we would need an English page similar to mine, that's right. But we cannot simply set up that page as it is mainly about real-world events. I understand that it seems strange to link a German page from an English page (if you don't have reason to assume that most readers understand German which is hardly the case here). But I have two aims with these hints in the KDE userbase wiki (and hopefully within Kmail directy soon). The obvious one: Helping Germans use OpenPGP by bringing those courses to their attention. The second one: Motivate people in other countries to create something similar. But this won't happen if the experienced users are just presented information links (which they don't need anyway) but are not faced with the fact that somewhere else something exists that they should copy.
Ideally we should have a link to a similar English page, but failing that I guess it's ok to link to the German one, as long as it is clearly stated. Hopefully someone will pick up on the idea.
Thanks for your work.
I just had an idea: I will probably get an international domain for a small English site which would just offer a list of national such projects and some help for people interested in creating one. That would be a better link target for the English article then.
