Are you refering to me :p
But I do agree it's annoying sometimes, we will change it in the new version, so that it will always keep the language on which you were before and the interface language will change only if you manually do that using the form at the top.

You can actually delete the language code out of the link. So for example, I have the interface set to Spanish. Sometimes I might forget and give you this link:

http://tatoeba.org/spa/wall/show_message/4974

But if I remember I'll give you this link:

http://tatoeba.org/wall/show_message/4974

which should redirect to whatever you have the interface set to.

Unfortunately, I think a lot of people don't know this, and a lot of people who do commonly forget.

Should be fixed. But your Google link is missing a question mark I think. It should be search?q=, not searchq=.

actually in swac-recorder you can precise this (in the "linguistic region" part of their interface), after it is part of the meta-information of the audio file, so with that we would be able to do so. In the future we can imagine to have the same things has swac-collection.org i.e several audio per sentences, and have the meta displayed directly (in a way or an other)

The real reason is because it would be more problems to deal with :P

Spam is one potential problem, but mostly it's because I don't really like the way email notifications are implemented and I don't feel like adding more notifications before the implementation is improved =/

But well, I guess we could start with sending notifications in case the sender or the recipient is a trusted user. If nothing breaks we can expand it to everyone.

In theory, to prevent spam.

Since admins can't read private messages (unlike comments), they can't see the spam.

Sorry, but the Russian is absolutely wrong.

Polish is wrong too, but my Polish is too bad to fix it («Ty» and «musieć» are not connected, «musieć» is an infinitive).

The German is wrong too, the verb is in the beginning, so it is a question. Also, German (and Turkish) is polite, other are not very polite.

Not very polite:
Russian: «Ты до́лжен написа́ть сло́во» (Tı doljen napisat’ slovo; pronounced [tı DOL-jen na-pi-SAT’ SLO-va]) OR «Тебе́ на́до написа́ть сло́во» (T’ebe nado napisat’ slovo, pronounced [ti-BE NA-da na-pi-SAT’ SLO-va]).
Ukrainian: «Ти му́сиш написа́ти сло́во» (Tı musış napısatı slovo) OR «Тобí тре́ба написа́ти сло́во» (Tobi treba napısatı slovo).
Belarusian: «Ты му́сіш написа́ць сло́ва» (Tı musiş napisats’ slova) OR «Табе́ трэ́ба напіса́ць сло́ва» (Tab’e treba napisats’ slova).
German: «Du musst ein Wort schreiben».
Turkish: «Sin bir sözcük girmelisin».

Polite:
Russian: «Вы должны́ написа́ть сло́во» (Vı doljnı napisat’ slovo, pronounced «Vı daljNI napiSAT’ SLOva») OR «Вам на́до написа́ть сло́во» (Vam nado napisat’ slovo, pronounced «VAM NAda napiSAT’ SLOva»).
Ukrainian: «Ви му́сите написа́ти сло́во» (Vı musıte napısatı slovo) OR «Вам тре́ба написа́ти сло́во» (Vam treba napısatı slovo).
Belarusian: «Ви му́сіце написа́ць сло́ва» (Vı musits’e napisats’ slova) OR «Вам трэ́ба напіса́ць сло́ва» (Vam treba napisats’ slova).
German: «Sie müssen ein Wort schreiben».
Turkish: «Siz bir sözcük girmelisiniz».

...?

Latin: Verbum scrībere dēbēs.
Tatar (not polite): Син сүз язарга тиеш. (Sin süz yazarğa tieş.)
Tatar (polite): Сез сүз язарга тиеш. (Sez süz yazarğa tieş.)

(Sorry, my previous message was wrong. Yazarğa is correct, yazırğa is wrong.)

Are you learning the reformed Volapük or the original one?
