Issue: Default 'Template' for New Article

Well, the main problem is that sections aren't editable easily, i.e. they aren't editable at all.

Did you try just to fill new articles with premade contents? I admit that I don't know much about programing but the process I see in my head is:

1. Admin or users with enough rights create template with some text (of course, text can have BBcodes in it, but BBcodes are just text before they are parsed).
2. User in process of creating article chooses first which template (kind of template I'm speaking of) to use, or not to use any (create blank article).
3. This text is just copied in a new article, but it's just plain text (at least from programs point of view, never mind that it has BBcodes in it). As I would paste it from somewhere else, I think you could program somehow that text would be inserted in article. And not some object, code construct, just plain text.
4. User fills that text with contents, as users do.
5. When user saves it, text gets parsed, as usually.
6. Now we have wiki article with working template, correctly parsed, someone else could edit sections and whatever else.

I think the key is that you treat my kind of template as plain text whole time and let parser do it's magic when time for parser to do its magic comes.

As I said, I'm not a programmer, but that's how I see it and I think that there are ways that enable you to put some predefined text (of course, admins and users with sufficient rights are responsible for text's meaningfulness) first and let parser to create wiki article later.

As this calls for different kind of template, I think that they should have different names. Let's say that we can call it drafts, as this is not finished article, but just draft of the future ones.

Also, user should be able to choose drafts somewhat similar like they now choose thread prefix (as starting wiki article is like starting thread). Only problem is, can you program that draft be erased if user changes draft after he sees that it isn't the one he wanted to use, and replace it with new one, or none, if user chooses so?

If it's possible, we would have dropdown list of premade drafts and as we choose them like we now choose thread prefixes, they would be put in text area. After user is satisfied with chosen draft, he would go and start writing article.

Even if you couldn't made drafts to be erased and replaced in text area with new ones just by changing what draft is selected, user could use 2 step process, first to choose draft (or no draft), drafts could have description (so users would know for what purpose drafts are used), and after he chooses his draft, confirms selection and goes to writing article.

We could also have options that some namespaces (or how would wiki zones be called as I read you'll drop namespaces) have drafts (maybe even preselected ones) and some are without drafts.
