Taking part in quizzes is easy, however creating them is a nightmare as the so called editors are overly picky and send back so called errors in grammar etc.
They are also extremely rude, I made the mistake of complaining about an editor being excessively picky and this was met with a rude reply.
Often the will send back with changes that need to be made, then when you make those changes they send another message that this change is wrong and suggesting you change it to what you already had put before. They seem to think they are English experts but often their suggested errors are not errors at all. They all seem power mad.
There is a chat/message board section that bans you for silly reasons, usually because you disagree with one of the higher ups.
This site is a rip off and I would not recommend it to anyone.
