If you're british, and 15+ y.o. (well, or less but you should be literate person and know almost all grammar) -> i'd be happy to pay you cubits JUST for fixing grammar mistakes in my english texts which i'll send ya.
I'm programming browser game, it's almost done, but texts written in english may have mistakes which can be noticed only by british people. I'll probably pay you per text or for whole job. You can earn up to 10k just for ~3 hours of work.
Maybe my request seems like it's "illegal", but it's not trading value or any other stuff between game. You help ME by lit waste of time - i help YOU for doing a favour :P
