I've heard a lot about this website: Workaway.info
I suggest that you do some research and write a review about it for others to know what to find and what not to find there. Why don't you pretend you are a journalist and write an article about it?
- What do they do, what's it for?
- First impressions, is it clear? easy to navigate?
- How do they attact people? Mention all the positive things that you like and found interesting.
- Have you got any recommendations to improve the site?
