## How do I search for text? Why might the results differ from what I expect?
=> [See article here](http://en.wiki.tatoeba.org/articles/show/text-search)
## Why are some translations in grey?
Grey translations are indirect translations. In other words, they are translations of the translations, and not translations of the main sentence (the main sentence is the sentence in big letters).
We display them because they can be useful, but you should be careful. Their meaning may differ a little from the main sentence.
## Why don't I see all the translations I expect to see?
If you have listed a series of language codes in your settings, Tatoeba will only display translations in the languages you indicated. Leave the field empty to display translations in all languages.
## Why are some sentences in red?
Red sentences are not approved. They raise copyright issues or are otherwise problematic.
You should not translate them.
## How do I delete a sentence?
Only advanced contributors can delete sentences. We may someday add the possibility for users to delete their own sentences, but in the meantime, if you want to have a sentence deleted, add a comment on the sentence asking for deletion and explain why you'd like to delete it.
If you have added something by mistake, rather than asking for it to be deleted, try to replace it by a valid sentence.
## A sentence is not marked with the right language. How do I fix it?
Click on the language icon to the right of the sentence and select the correct language from the list.
## How can I add tags to a sentence?
To add tags, you must be an advanced contributor (see below).
## How can I link or unlink sentences?
To link or unlink sentences, you must be an advanced contributor (see below).

## When contributing in Chinese, should I use simplified or traditional characters?
You can use whichever you like. We have a tool that will automatically convert simplified into traditional, and traditional into simplified.
When browsing sentences, if you set the Chinese sentence as the main sentence, you will see an additional icon at the top of the sentence.
Below each Chinese sentence, you will also see the transcription in pinyin, and below the pinyin, the conversion into simplified or traditional.
You can browse the Chinese sentences to see what they look like.
