Question problem with viewing the forum

hello!
i use kunena on my site www.gumno.neum.info , and when i log as administrator, i can see all categories and everything, but when i log with my other account ( with author rights in joomla), i cant see damn thing...
i mean, i can see front page of the forum, but cant see categories or anything...
can u help me an tell me what to do...i guess that i need to set some privilegies or something...
also, if it helps, i set up that guests cant view the forum...

here is the picture of what i see

Each single categorie and forum have to be configured with the Access levels....so for example the accesslevel is set to regiestered users the categorie will only be show for registered since you aktivate "include child groupes" then also authors and publisher can see that forum.

Same for the admin access level setup....

Also remember to publish forums!
