Importance Ratingsplugin-autotooltip__plain plugin-autotooltip_bigImportance ratings

In a departure from the usual Wiki format, Wikenigma assigns 'Importance Ratings' to some pages.

The idea is to separate articles which are considered (by the editors) to cover exceptionally important unknown issues from those which (although also u…

Frequently Asked Questions

Q. Why the weird syntax?
A. Like most Wikis, the site doesn't use HTML for formatting (security reasons etc). A guide to the special syntax can be found hereplugin-autotooltip__plain plugin-autotooltip_bigFormatting Syntax

There are two ways to edit pages, the default Visual Editor, which is more intuitive, and the more comprehensive Syntax Editor.

( You can switch editors with the 'Switch Editor' button at the top right of the page )

Visual Editor
. Unfortunately it can be quite confusing at first - but there's now a new 'Visual Editor' system which greatly simplifies things. Best rule - keep it simple.

Q. Why didn't you use the MediaWiki core like Wikipedia?
A. It's heavyweight software designed for very large wiki implementations. Currently beyond the scope of this site.

Q. My pet goldfish died and no-one seems to know why - can I include it?
A. Probably not. But if there was an unexplained epidemic of goldfish deaths that had been mentioned in the media, then yes!

Q. Why is there no technology section?
A. If a man-made article has a behaviour which no-one (not even the designers) can explain, let Wikenigma know, and it'll be up-for-inclusion. Amazingly, there are some examples - see for example Neural Networksplugin-autotooltip__plain plugin-autotooltip_bigNeural Networks

first. Once you're a registered user, the easiest way is to use the 'Create a new article' link (above left).

Q. Why can't I edit this page?
A. Some pages, like the site info pages, aren't available for public editing - but you can of course edit any of the content pages, or create new ones, if you're a registered user

Q. Why are there dead links?
A. Unfortunately, links to external websites sometimes fail - usually when the target website changes the location of where the page is stored (or deletes it). If you find a broken link, let Wikenigma know! Sometimes the page has just been moved, and the link can be updated. (Note: the site has an automatic external link-checker - which finds most of them)
