Wikimedia projects. For more then 280 languages there is a Wikipedia and finding someone with whom you share a language is powerful. It helps building communities particularly for the languages that have a small footprint on our servers.
At translatewiki.net we are always on the lookout for people who localise for a language that does not have the Babel extension localised. We do ask people to give priority to localise Babel and typically we are happy with the results.
We asked people to localise Babel for the Kirghiz and the Kongo language recently and both have been localised.
Have you checked if the Babel information is correct for your language? Do you know a language that may not have a translation for the strings indicating your proficiency in the language? Please check it out at translatewiki.net.
