Always free to RP (That rhymes)
Hi, dear, and I apologize for the very, very late reply, and I don't even know if you already grasped some information on claiming, but just to be certain, I'll be explaining it to you in the simplest way I can.
Go to the claiming page, and under the Claiming header, type the name of your character in the box and click Get Claimed. This will open up to a blank page. So you have to go click the upper right button in the page, which says Edit. Once in Edit mode, you can now create your claim (follow the instructions on the template in the claiming page). Then Publish it. Don't forget to add the category 'Claiming', oki?
So, that's just about it, and message me again if you have any questions. :)
