Wikis

I like how that one site had the pros and cons listed for having a wiki. This should always be considered before starting a wiki site. Also I found sites that have not been added to since, 2006. This information is old and the site is no longer being maintained.

A wiki site takes time to be able to take care of. If you ignore the site you can end up with a lot of links to sites that are trying to sell items. Do you want your wiki site to be an advertisment drop point? At least once everyday the site would have to be checked for changes, add on, and what it is all about.

Could be useful in information about your community so people can post an event that is going to be happening.
