I'm now working on a new open source translation project which is FireGPG. It's an extension for Firefox which can be used as an interface to GnuPG so it enables the users to do operations which can be done by GnuPG, such as encrypting/decrypting emails, signing/verifying signatures, and so on.
I have requested the role today and i'm hoping to finish the translations by tomorrow or the day after tomorrow. Currently, there are still 137 strings to be translated and it's possible to have Indonesian language on 0.7.8 version when it's released (unless major problem occurs and the author is expected to release 0.7.8 earlier than expected).
Update (19:28): I decided to finish this translations today and it's already reached 100% now. Indonesian language should definitely be available on 0.7.8 version.
