I have translated Gravity Forms to Swedish. All strings are translated and so far I am satisfied, but will for sure want to change some translations in the future and after more testing.
Those of you who will use the plugin with Swedish translation, if you find any oddly translated strings, please let me know and I will correct it and try to keep the translation updated with every new version.
I have encountered one bug so far. Its in the admin css where ul#gf_form_toolbar_links li.gf_form_toolbar_settings has a fixed width of 103 px. The width should be auto, so that the translated can have any length.
Where do you want me to send the PO and MO files?
Hope you enjoy the translation!
