It's probably because we added some features (sending the first message) and the translations are not up-to-date anymore.
The fix is simple:
Click on the English language flag in the upper right corner of the spamgourmet page.
This will select the English pages, which should work.
The French and German pages are translated, at least partially.
If you are a translator, please take a look at the new English pages. Contact Josh for more info.
