It looks like we have volunteers to translate things into Swedish, French, and possibly German at this point.
Still need Spanish, Czech, and Polish. Might as well throw in Russian as well since there is a pretty large Russian OFP community.
The entire readme wouldn't need to be translated. All that will be required is the general set of features listed in the first post, the install instructions, credits, and troubleshooting part. The change log can be left out since it has grown to be the largest part of the readme and is mostly of interest only to people that want to know what has been fiddled with.
