I just added support for 3 new file formats.
PHP Define files
I added support for PHP array files months ago. You can now import PHP Define files, which are also popular for localising PHP applications.
MicroDVD and Subviewer subtitle files
In addition to the existing YouTube .sbv and Subrip .srt files, WebTranslateIt now support MicroDVD and SubViewer 2.0 .sub files.
This makes a grand total of 30 different linguistic file formats you can translate using WebTranslateIt.
