Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

  A - B - C - D - E - F - G - H - I - J - K - L - M - N - O - P - Q - R - S - T - U - V - W - X - Y - Z 


A

Administrator
A user with a few extra privileges such as deleting pages, protecting pages from editing and blocking users.
Alphasort
Contraction of alphabetical sort
Article
A page in the main namespace.
Article revision
A revision of an article.

B

Base page
The opposite of a subpage.
Block
An editor can sometimes be blocked. Could for example happen during an edit war, after spamming etc.

C

Category
A category is something between a directory in a directory path and a tag, as a page sometimes can benefit from being in more than one category. Adding a category to a page is a way to organise the articles and put them in a larger context. A page is added to a category by adding a link to the category on the page, like [[Category:Help]], preferably at the end. To link to a category without adding a page to the category, the page name is preceded by a colon, like [[:Category:Help]].
Category diffusion
Breaking up categories that over time have gotten too big into smaller ones, often as subcategories to the larger one.
Category page
The page in the Category namespace where the categories resides. Should preferably only contain a description, base categories and sometimes one or more templates.
Category sorting
A page can be sorted under a different name by using a sort key like this [[Category:Category name|Sort key]], for example [[Category:Boeing|707-320]]. If a page is in many categories the magic word {{DEFAULTSORT:Sort key}} can be used at the top of the page instead.
Category suppression
Suppression of automatic categorization by templates, usually depending on the page namespace. Some templates uses category suppression to only add a category to a page if it is in a certain namespace, for example the Main (article) namespace.
Cat sort
Contraction of category sorting.
Copy editing
Editing to improve the formatting, style, and accuracy of text, but usually without changing its substance.

D

Diff
A comparison between two revisions of a page that allows a reader to see what was changed, added or removed from a page.
Discussion page
Synonymous to a talk page, a page in one of the talk namespaces.
Diffusion
See category diffusion.

E

Edit
To change the contents of an article. An edit is saved into a new revision of a page.
Edit summary
A short but meaningful summary of an edit to be show in the revision history for that page.
Edit war
When two or more editors battle each other, most often by changing some text back and forth. Will often lead to that the editors will be blocked temporarily to calm down a bit.
External link
  1. Link to content outside the wiki.
  2. An internal link that is not a wikilink, like for example permalinks.

F

File
A file, usually an image that can be used on pages by linking to it, like [[File:Thumbs up 32px]].
File page
A page in the File namespace containing information about a file, usually an image. Since a normal link will show the file, a colon must precede the file name in order to link to the file page, like [[:File:Thumbs up 32px]].
Lead section
The lead section in an article is one or more paragraphs of text preceding the first heading. The purpose of the lead section is twofold: It should give the reader a clear indication as to whether he have found the right page and it should give him an quick overview of the concepts of the article.
