Hello CzechOut, and welcome to the RuneScape Wiki! Thank you for taking an interest in our wiki.
Here are a few pages to help out new editors such as yourself:
If you have any trouble or need help, feel free to ask questions on my talk page or any other editor's talk page.
You can add other fonts to your wiki by creating a page like [[MediaWiki:Common.css/Webfonts.css]] and importing it to your css files (common.css and wikia.css). The page needs to contain atleast a base64 encoded version of the font, and possibly downloads for some browsers so they can put the font in the cache. You can search on google on how to get these things (there are some tutorials or guides spread around the internet). The dropbox address is an url from which people will download the font file. Dropbox is used as a kind of "host" for storing the files on. You can host the files on any server that allows public accessing. A page where the fonts that are installed here is for example my user talk page. If you hover over the "Walk here (6 more options) ▸ " at the top of the page, you'll see a popup where the runescape font is installed. You can see more about the template I'm using for that at Template:Choose Option. JOEYTJE50TALK pull my finger 15:02, January 14, 2013 (UTC)
