I'm familiar with how to hide a forum (or not)
The knives forum was hidden for a reason - aka in their theme of secrecy.
However, I really like the idea of displaying the guild forums, and personally if I can see a valid application (ie a thriving guild) I will be honouring my previous statements that I will be creating more.
I personally think that, for a potential new player to log on and see a thriving guild forum section, this enhances the 'community' feel. After all, the web is full of admin-generated generic content - that is why the latest .com explosion is in user-generated content. I don't mind showing publically that Obsidian welcomes community cohesion.
The guild forum section will remain displayed as is.
PS. The 'scrolling through' is exactly the reason they are placed at the bottom.
