Ok .. let's do some magic .. have you ever worked with POedit? If yes .. create an en_EN.po from the thematic.pot. This file can now be 'translated', means you can change 'Meta' to whatever you want without changing a single line of code. Copy the en_EN.po to languages .. that's it.
If not .. let me know what you would like to see instead of 'Meta', send an email to chris (at) wupperpiraten (dot) de, I'll change the file, send it over to you, you copy the file to the languages directory .. that's it.
Magic tested and approved :-)
Cheers,
Chris
