mwForum has a tree view, and looks pretty nice too.
That looks pretty simple. It would probably work.
I think that features can probably be removed when creating new phpBB templates. It seems like there are placeholder tags used for the various options, and if you leave those things off the template, the options wonāt appear. I could be mistaken, though. In the long run, people would probably become power-users and this would all seem really simple. Initially, though, I think itās just too much. 
Hi all,
No offense intended here, but itās getting to the point where the meta-discussion of the forum - the software used, the boards to implement, etc., is overtaking the intended purpose, which is to discuss IF, and itās a little tiresome at this point. The debate over which board engine to use seems a little pointless. I havenāt noticed any āsteep learning curveā in figuring out how to a)register or b)post a reply. It seems this is just a point of personal preference for many people, and thereās no āobjectiveā better or worse, unless you want to start comparing things like security (the lack of which which phpBB used to be notorious for).
In the end, I donāt really care, and suspect many others donāt, either. How bout we get on with things here? Merk is a particularly active member of the Hugo forums over at Joltcountry; perhaps he can kick things off with some Hugo tips n tricks, in the process silencing those heathens who would do away with a dedicated Hugo board here.

Well, if thereās a chance we might change the forum software, it might be a mistake to get too much real discussion going. Itād be lost, probably. Plus, with different opinions on what should and shouldnāt be here to start with, Iām starting to feel bad about rushing into this.
*Edit ā yikes, my italics bb code tags show up as garbage, instead of italicsā¦
