Georgem: I think a German translation is a good idea for the same reasons others gave, if the additional management is not too much hassle. But if it happened think it would be best to wait until there's a section on the portal (like a FAQ) which makes clear devtome is in english only.
I think it would be a pity (and wrong) to have devcoin only allow english texts.
Imagine wikipedia in only one language?
Is it atleast thinkable that we have english texts but also some kind of
translation departement that coordinates the translation of all those english texts?
So every english text
can have translations. But no text can exist in german only, since there always
must exist an english version first.
That would be easy to manage database- or id-wise. Since there is always the english text as parent-node, and all the translations of this parent-node are simply child-nodes and can't ever be parent-nodes.
