Features / Usability

You have to edit the stylesheet file for the theme that you're using.

Eg., I use the theme moreneat. So I'd have to edit the file /styles/moreneat.css

In moreneat.css, I look for the lines

/* Links to wiki pages */
.wiki { color:#335966; text-decoration:underline;}
.wiki:hover {color: #436976;text-decoration:underline;}

Just replace "#335966" with the code for the colour you want wikii links to render in.

Another useful thing you could do while you're at it is add a line that will justify all your wiki text.

You do this by including the following line in the "div.wikitext" section

text-align:justify;

Hope this helps.
