I called this function in my script
GForum::Forum::tpl_list('hide_user')

However the reference it returns seems to be missing some stuff.

Everything tallies with what I get in that big "Everything" loop in category_list.html
except for the following 2 keys
{'forum_new'} and {'forum_permission'}

The $USER reference is initialised correctly.

Do I need to call another function to get those keys in?

Thanks.
