I have seen Translation Campaigns that requires you to put your previous works/translations. Is there any chance for a beginner, who doesn't have translations yet, to join this kind of campaigns? If yes, how? Thanks!
Most likely, without a portfolio you will not be able to take part in the translation in perspective projects. But I think you can take part in less significant projects, fill your portfolio, and later this will give you the opportunity to make a transfer in any bounty that you want
