Forum to single Post link?

If you had several sections in a forum and wanted them all to all point to one specific thread, whats the best way to accomplish this?
Example: Lets say you had a forum for Gaming. In that forum you had it broken down into Video Gaming, Board Gaming and Out Door gaming.

And wanted to post "How to select a Great Game for a get together". You make a post in each section. How would you make it so that whenever a member went to any of those link they would just redirect to one specific post?

FYI-- Just trying to not post the same answer in each of the three sections.

Thanks is advance for the help!
