Comments are used to provide user-feedback to many Tiki features. Users can comment on Wiki pages, image galleries, file galleries, articles and polls. The comment system can be configured to allow users to vote on comments. A karma system mantains a level for each user. The level improves when a user comment is voted on by another user. Good qualified users votes add more points to a comment than users who didn't get good qualifications. Comments can be displayed/hidden using simple controls and the user can control how to sort votes, the number of votes to see by page and the minimum threshold (score) for a vote to be displayed.
