Github is not very friendly for newbie, so take your time GazetaBitcoin.
Recently we, in the portuguese community, created a new Pull Request for BIP39 Portuguese Wordlist and it is waiting a few weeks/month already.

My suggestion is that you take your time and send the pull request only when it is absolutely ready. Do not make many commits, work in your computer and submit your work when it is done and revised.

I believe this is the romanian translation which you need to fork and make the pull request
