Are you multi-lingual? Are you willing to give something back? Would you be willing to translate UpdraftPlus into your language and help other users?
The process is easy; we've written up instructions with screenshots, here: http://updraftplus.com/translate/.
If you also translate the phrases which are part of our paid add-ons, then we'll give you free vouchers for UpdraftPlus Premium - with life-time updates. What are you waiting for?
