Pros and cons from what I can see:
Forum-based
Pros: It's already setup. Everyone here knows how to use a forum.
Cons: Editing a large post, like KissAssist Manual or the Macros Wiki is daunting. You can't edit one section, you're faced with a screen full of code.
Wiki-based
Pros: We can easily edit entire sections. Searching a wiki is easy. We'd also have the users/passwords to be the same on both forums/wiki.
Cons: I don't have the patience to make the css look exactly like redguides, so it's going to look like a wiki.
