Must I translate the internal links «Special:X/Y|X»?
Thanks a lot for bringing this up and remind me of a task I should have done long ago! Shame on me! The links should indeed be translated too for best experience. Translatewiki.net configuration has to be changed to stop the link checks you are referring to and thus allowing to translate. I will author the change and give you a note here as soon as it is doen.
I have now authored the configuration change. From experience this should not take long to be merged.
Don't worry, Karsten! There is many things to do and it is normal that we forgive something and enter in a loop of oversight things hehe, it also happens to me. Just a note, it also should change too in the strings in which is
[[Property:*]] or similar links.
All right, I will be awaiting for your note here. Don't be hurried!
You need to allow some time for the merged settings to roll in. This is why I have not yet notified you. I believe everything should be fluffy now. :)
Oh, I was desperate to check the change hehe, excuse me! Yes, not it is fine and it doesn't detect as fail the correct format. I already translated all the SMW's strings, so tomorrow I will try to begin to review all the Spanish translation, because I have detected errors that have to be fixed, some of them are not very alarming, but there are another that have to be fixed until of the release of SMW 3.0. I am expecting the release, I want to do the best as possible, and what I can, to collaborate and improve SMW :).
That's the spirit! :) Thanks a lot for your involvement!
What just comes to my mind: Never ever change the link [[Special:Types/Date|type]] to [[Especial:Tipos/Fecha|tipo]] because in this case everything breaks for people that use Spanish on a non Spanish wiki. You can only do [[Special:Types/Date|tipo]]. I think that adding an alternate label was possible before so disabling the link check was a pretty bad idea since it will do more harm than good.
Oh, true... Excuse me, Karsten. I will fix it in TranslateWiki. I will notice you. I am busy now, but I will do it and the Twitter issues soon.
