Replying to [Admin]:
I have a suggestion.
why don't you (Moderators) give us some trivia quiz as other version of question riddle. this trivia should be related to each previous post.
the content should be rich and has specific topic for each chapter. we can make 5 to 10 post per chapter. Of course all related with English.
The easiest sample of my thought is something like a reading article session. Then each members who reply to the post must find the answer of each question given on the reading.
Since this would be sounds easy, maybe the article should be in form of a quiet complicated story, but not that complicated since we all want to learn English with fun without headache. Some kind of detective story for example. the best conclusion post will win big MVPs.
I guess this will attract more members to contribute.
For the article itself perhaps Professor Carl or other linguist here can supply us.
