[TYPO3-english] mm_forum - how to link forumpage into the only forum and not the forumoverview inside the category

[tfpgs]

i got a forumpage with the mm_forum main module.
when visiting this on FE you get the forumoverview, with only one existing Forum.
I want that this page links directly into the only Forum and shows the threads inside that forum.
its very annoying for every user to see the inside of the category when only one object exists.
instead the users should be presented the inside of the only forum.
thankx!
