One thing that ive been missing on the forums is tree-like navigation for forums and sub-forums, at least at the top of the page, and maybe at the bottom too

something along the lines of:

SilverStripe Forum
-> Feature Requests
-> Topic

The main thing holding us back here is developer resource. Would you be able to help out with the implementation of this?

ill see what i can do with it
i havent played with the forum module much

does anyone know off the top of their head whether or not <% control Level(x) %> would work for this?

Kind of. It would be better to get the forum holder with a function like this:

function GetForumHolder() {
$obj = $this;
while($obj && $obj->class != 'ForumHolder') $obj = $obj->Parent();
return $obj;
}

And then use <% control GetForumHolder.Children %>
