First, I must say that this really is one of the better e-commercer plugins we have tried, so thank you.
So there are .po files that we can use to translate, however after a short google session, it seems there is no repository/collection for users to submit their language files?! Our thinking is like this: Before we translate into German, check to see if someone already has done this (surely yes). If so, 1) why are the language files not included in the plugin. 2) since they are not included in the plugin, where might they be? Finally 3) If the language files are not available any where, does WPMUDEV want to deal with offering this to the community?
