This doesn't currently work… I'm getting this error:
```
A database query error has occurred. This may indicate a bug in the software.

* Query:
    SELECT tmi_value FROM `translate_messageindex` WHERE tmi_key = '-1:createWiki' LIMIT 1
* Function: DatabaseMessageIndex::get
* Error: 1146 Table 'foo4wiki.translate_messageindex' doesn't exist ([redacted IP])
