I've been wondering on how to do translation and what are the requirements to be accepted in this job? Also Can you advice on what bounty campaign I can apply for the beginners please send some help.
Participating in a translation campaign really needs an experience and harder to apply. But if you're really interested with this kind of job, then you can do for free service for several campaigns just to earn some experience that will help you a lot to find a client in the near future.
Not only for translation there are many things that you need to be experienced because bitcointalk always need experience person. Bounty section, translation, a signature campaign etc always need experience for participating those.
