Blog Topic question: blog user can't change topic

Hi,

I installed Blog Topics For WPMU (http://wordpress.org/extend/plugins/blog-topics/)
This works great but I have one problem. The blog users and the admin can't change the topics of the blogs. Adding works good but in the Admin the submenu for changing the topic doesn't show up.
I'm using WordPress MU 2.9.1 with BuddyPress 1.1.3 and I'm relatively new to WPMU.
Can someone please point me in the right direction where to look?
