Welcome to the Wiki! And some useful tips!
Thanks to everyone who has joined the Wiki recently! We're already off to a great start to the Wiki Editing Contest, which runs until 20 May 2016. 
For new editors, I recommend having a look at this link which explains the basic features of the Visual Editor, which is the default editor on Wikia. If you're not sure how to add a link, this is the place to go.
For those who are more adventurous, and really want to make a page look the way they want, you can try the Source Editor, which uses the Wikitext markup. You can read about the basics here. This is what I personally use.
If you need any further help, feel free to message me on my Message Wall, leave a comment here, or a PM on the official forums.
