I am looking for some advice on wikis.  We have a special ed teacher that wants to use a wiki to do a project with her students and has no experience with wikis.  I am looking for a wiki that has a minimal (preferably none) amount of advertising and a really simple, uncluttered interface.  I am also wondering if there are wikis that can be configured to allow a moderator to approve edits before they are actually visible.  The teacher is concerned that there may be some 'vandalism' to the page if edits are published automatically.

Will the Riders host a playoff game?

While the Riders got off to a tremendous start they have faltered of late. The expectations created by the early successes are certainly being tested by the recent struggles. What do you think. Will the Riders reverse their fortunes and host that elusive playoff game?
