We used to have sidebars. We got rid of them because it's terrible web design
Here's 2011.
Wow, I remember this one! (I was a long-time/sporadic lurker back in the day)
Understand that if we decide to do that, we essentially become a wiki. And we can't become a wiki. What we need to do is find a way to present this information that's intuitive and doesn't send a person's eyes searching for the usual wiki tools, because we can't be a wiki. (That was another reason we didn't do this, because FFWiki already exists). Although it's an idea I'd like to revisit.
Would perhaps a new forum under the "Compilation of Final Fantasy VII" section achieve something to this extent? It would be one dedicated solely to asking questions regarding the player's/asker's uncertainty around terms, why X happened and how come Y made sense in relation to Z.
Because it will be in this format of a forum, it engages members to help one another; perhaps it will even encourage the new members (who signed up to ask a question) to stay on and get involved.
Of course, it could end up inundated with complex questions that do not have a definitive answer (the kind of ones that appear in the "Final Fantasy VII" section every so often), but it would certainly help highlight why their question is such a troubling matter in the first place.
If anything, its sheer dedication to basic explanation, clarification and elucidation makes it that bit more open and inviting as a stopping ground for those who want to quickly check for something they aren't sure about it (or even end up asking themselves).
Indeed, it would be, to a degree, unrivalled (especially if there is a harmony of responses that build the foundations of well-grounded information)
Naturally, it could all end up as a messy mass of no coherent information, as well as a lot of work involved keeping it organised - a "Sticky" thread could be created with a link to resolved questions (i.e., ones with insightful information) that successfully explained certain terms, events and correlations etc., but even then...
This is just a "ball-rolling" idea if trying to avoid a typical Wiki/Encyclopaedia route (it's almost like a "forum-engaged encyclopaedia", where discussion brings about knowledge - a bit airy-fairy, but sure we're an open bunch) - so, please forgive me if this is an asinine suggestion
