[support] taxonomy vocab relation question

Hi List, I have a vocab called class, with several terms representing different classes . Each class, has a forum and an image gallery. These are in seperate vocabs though (drupal creates a new taxonomy when you create a new forum or image gallery). Is there a way to logically link/relate vocabularies so that I can have links to 'class forum' and 'class image gallery' from the class room page? I know this can be done using regular expressions but am wondering if drupal handles it in a better way. Thanks, V
