Question by HappyDog: «However, one does have to question why we use the wiki for these purposes at all. We don't use the wiki for internal issue tracking, so I'm not sure why we are using it for support. I am not aware of any other company or open source project that would consider using a wiki for handling support issues - it is clearly the wrong tool for the job».
What software/site to use for https://www.mediawiki.org/wiki/Project:Support_desk ?
