1. Be sure to be active. I'll be sending e-mails every now and then for updates. Don't worry, I won't spam your e-mail though -.-
2. Be friendly to others especially to our requesters.
3. Inform me any of your concerns. I'm just one e-mail away. :)
4. You don't need to be really good in English. As long as you can speak the language, you may join. But be sure though to improve your vocabulary and grammar skills every now and then. :) We're all not perfect and that includes me.
5. Be a good muse with your requester. Remember, you're a professional writer. You give them good ideas on what to write next. Let's all be reliable. :)
