Anyway, the challenge is open early and it is over here at AO3. The window for signups does not change, so you have until 15 May to make up your mind about who or what you want to ask for or write about. As I understand not everyone is familiar with AO3, beneath the cut is a pictorial representation of how to do it. It's pretty picture heavy, so heads up.
To sign up you go to the left and click "Sign up form". You should see two boxes, the first one looking like this one:
This is your request section. You are allowed two requests! This is to maximise matchings, especially given that we have essentially two interconnected canons.
To make things easier for the matching algorithm you are only allowed one fandom per prompt. You can duplicate fandoms (for example you can ask for up to two prompts for Young Wizards or vice versa) but you can't mix them up and have two fandoms in the one section.
So you want a Young Wizards story as your first prompt? Start typing "Young Wizards" into the Fandom textbox and you should see this:
If you want a Feline Wizards story, start typing "Cats of Grand Central", where you should see this:
For the rest of this section of the tutorial I'm going to use Young Wizards as my example, but the same should apply for FW.
Now, moving onto the character section. This is kind of complicated. 0 characters means that it's a kind of worldbuilding thing; you can request some details about alien wizards or wizards who live in volcanoes or what have you, though you run the risk of not being matched and being asked to redo your sign up. If you tick the "Any" checkbox you have said that your writer can write about whatever character they like. This could mean you get the story you never knew you wanted, but if you want a story about particular characters, this is not the option for you.
Anyway, if you want a particular character, you can start typing in the character field the character's name. There's characters already present, so choose your character off the list. It should look like this:
There are obviously more characters on this list, I just cut it off across poor Sker'ret's name because I figured we had better things to do.
Anyway, next is the "Optional Details" part. There are two types of optional details. The first is not really optional at all, in that if you request no NME or tumblr material (or just one or the other) your writer must respect that. The other is a prompt or sort of inspiration to help your writer get an idea of what you would like from your story. This one is optional, and your author is not obligated to follow it. Though, of course, most authors will do their best to!
If you would like to do a second prompt, click on this button (it goes red like this screenshot when your mouse hovers over it, like mine was.)
This is where you sign up for what things you are willing to write for.
As you can see, the character thing is different! In this challenge you must offer to write for at least two characters or check the checkbox that says you will write any. Unlike with the requests, where the characters you select must be in the story, in the offers section you could get assigned to anyone who has at least one of your characters chosen. So if you're not comfortable writing S'reee, for example, don't put her down, because you could end up writing for the person who wants Nita and S'reee fic.
Also, the second offer here is only for if you are offering both Young Wizards and Feline Wizards. If you are only offering one of them, you do not need to make a second offer.
If you need an invite to AO3 drop me a comment, or private message me either here on LJ or on tumblr as crankywhitemage and I'll do my best to set you up. Other than that, feel free to ask questions, poke around and if you're interested, sign up!
Also! If anyone would like to beta, feel free to offer in the comments :)
