hi.. friends

I have a scenario here to test an internal forum

There are certain things i have taken into account, if some validation or test case are missing please guide me....

1. The user should be regsitered in the site

2. The user login should be approved by the administrator

3. The user can post the queries

4. Initially we have to create multiple logins - so that one can post the question and other answer for the question

5. Moderators or registered members of the site can answer for our the posted questions

Thanks in advance,
