@humphd  I'm thinking of maybe if we have some pieces of the string that is separated from the sentence and another one the whole sentence (without markup), so when the users doing the translation they will have a sense of what the single word might look like if they are putting together in one whole sentence.

If my idea wasn't clear this is what I meant. 

Original

`We're a global community that doesn't just use the web, we <em>make</em> it by creating, remixing and teaching. 
<a href='/login'>Sign up</a> and start making!`

What we might do is

 Separate them into pieces

1. `<key>We're a global community that doesn't just use the web</key>`
2. `<key>we</key>`
3. `<key>make</key>`
4. `<key>it by creating</key>`
5. `<key>remixing and teaching</key>` 
6. `<key>Sign up</key>`
7. `<key>and start making</key>`

And we might also include one with the whole.
