So, the main role of a CA is to help contributors and supervisors do their stuff: asking, answering and editing questions.
Here are just a few activities that CAs perform daily:
Yes, Community Assistants are paid employees of the Answers corporation.
All Supervisors and Community Assistants can give warnings on WikiAnswers.
The Community Assistants have the most power.
WikiAnswers is owned by answers.com. The highest users on this site (they work for WikiAnswers/Answers) are the Community Assistants.
Community Assistants can be contacted via their message boards or emails.(See the Related question for the full list of Community Assistants.)
Zanbabe (Suzanne) (http://wiki.answers.com/Q/User:Zanbabe) is currently the only community assistant on WikiAnswers.
Yes, the Community Assistants do get paid.
Yes they are also known as community assistants
The highest contributor level on WikiAnswers is Ruby Contributor (500,000 contributions or more). Community Assistants (Answers.com employees) could be considered the highest "ranked" on WikiAnswers. Scott Moore (username Struwwelpeter) is the head of the Community Assistants.
Only Supervisors, Community Assistants, or employees of Answers Corporation have WikiAnswers email addresses.
As Community Assistants are paid employees of the Answers.com corporation, they likely must be online during the times assigned, or enough to fulfill requirements; work time depends just like any other job. Of course, this does not mean that Community Assistants are on WikiAnswers solely due to their jobs.
Community Assistants are paid employees. Anyone else that contributes to WikiAnswers is doing so voluntarily.
