It's not really a bug, although I understand it can be confusing... I guess we'll have to rethink the display of the latest contributions.

The thing is, what we display in the "latest contributions" is actually the logs. When you add a sentence, it also adds an entry in the logs, with the text of the sentence and the language that has been detected at the moment you have added it.

And since logs entries are not supposed to be modified, well, they are not updated if you update the language of the sentence. (We don't log language modifications)

It's a bit annoying now because Google has changed their language detection algorithm and a lot of sentences end up with an unknown language :'(

Anyway this weekend the whole team is going to gather and work on Tatoeba, and we're going to introduce the possibility to set the language of the sentence manually (instead of always having it auto-detected).

Yes, we can. I can't guarantee it will be done before this weekend though (as far as I'm concerned I have a busy week).

In the meantime however, you can always add sentences in Czech, even if Czech is not yet "officially" supported.
Your sentences will be categorized as "unknown language", but later (once we add Czech) you will be able to specify that they are Czech.

Thanks to take time to add your languages :D
but could you just respect a convention
begin sentences by an upper case and finish by a period :
"I love you." instead of "i love you" , it's just to make detection of duplicate easier, thanks :)

Bugs are fixed :) Thank you for reminding !

yep, Trang and the others have made a good job for it :)

Yep you're the first, feel free to report any bugs or strange behaviour you see :)
