Tags, wikilinks and stuff

There are certain tags which will effect words they are "wrapped around":

Formatting of words

The ' are used in formatting words:

''Italics'' (2x ') will make Italics

'''Bold''' (3x ') to write in Bold

'''''Hi all!''''' (5x ') will print Hi all!

Placing headlines

Headlines come in various sizes.

To avoid making this article impossible to read, the headlines-section can be found at Help:Editing/Headlines

How to wikify

This is probably the most important of the tags. To wikify a sentence means to make the sentence link to the corresponding article on the mersennewiki. This is done by putting [[ and ]] around the word.

An example:

"The person who runs the [[GIMPS]] project is [[George Woltman]]"

will make:

"The person who runs the GIMPS project is George Woltman".

It it also possible to link to another article. That is done by using | inside the [[ ]] to seperate link and word.

An example would be:

"Certain [[Lucas-Lehmer test|tests]] are used in [[GIMPS]], which is the biggest mathematical [[Distributed computing project|project]]"

which would turn up as:

"Certain tests are used in GIMPS, which is the biggest mathematical project"

Links

To add a link to a page outside mersennewiki you could either just type the URL:

"To get more info, please visit http://www.mersenneforum.org"

or you could make a description by putting it in the form [link title]. That would turn

"To get more info, please visit [http://www.mersenneforum.org the Official forum]"

into "To get more info, please visit the Official forum"

Math symbols

To write mathematical formulas, insert <math> and </math> around your formula.

For example

"The [[Sierpinski problem]] is about numbers of the form <math>k*2^n+1</math>"

would show

"The Sierpinski problem is about numbers of the form [math]\displaystyle{ k*2^n+1 }[/math]"
