It should be stretched by default. All pages are, and even the Main page's talk page is. Even one of the old versions of the page is... hmm.... idea! Will copy new version, rollback to oldest version where its stretched, and then paste in current code. Let's see if that works.....
Anyway, I already contacted Wikia central about it, so if it doesn't, we'll see what they say.
Anyway, atm, I am creating templates, including the MUCH needed info box, which is basically the most important template known to man. You know those boxes in the top right hand corner of an article, such as on wikipedia, which hold information, and can often be used to compare things with the same type of box? That's the infobox.
I'll also make a specific faction, tileset, etc; infobox, so in the future, we can have those on each page.
EDIT: That won't work... the revisions no longer stretch it.
Another EDIT: Wow, adding all these templates isn't easy, because the Wiki was made long ago, and is missing the default templates, so I must add those by hand too... Still, the info box template, documentation template (this isn't for use in articles, its to display the documentation of templates themselves), and CC-BY-NC template are up. Feel free to test them!https://docs.megaglest.org/Template:Infobox
EDIT3: Success! here's the full list of templates:
Next I'll make faction, tileset, and map templates. But first, documentation is missing for most of these, so....
Another EDIT: Documentations added. You may need to click the refresh link at the bottom of the documentation window to see them.
