I am Lithuanian, so I would probably like to make some posts in Lithuanian (I know there is at least one Lithuanian post already). It might be a problem if you are searching for something in particular and probably don't want to have search results in all the different languages, but I think the problem can be solved very easily. Just put a sort of warning in the topic (like in the (lang: lt) CGI/Perl Script Security – „lang: lt“) and then add a capability to exclude those posts in the Super Search. Then we would only have to agree on the language tag naming conventions ;)
