Okay, so it's another world that anyone can access. So it's more of a free-form, non-plot driven place where we shape the world as we see fit? But I do assume that there are things like missions for the guild and in the town. Maybe even add a crisis so that the players come and work together to avoid said crisis.

Well, the site is pretty basic. I mean, you already got the hang of quoting and mentioning. The options on the reply box is just basic HTML. As for roleplaying, well that depends on you. Well you can respond after everyone had posted (when doing a GM post where you detail what is happening around the characters, what they should be seeing, controlling NPCs for other characters) but you can also post after someone who is interacting directly with your character.

It also entirely depends on you if you want to go with a posting order (where you assign who goes first and then the next and then the next until everyone has posted) or you can just let the users post whenever they want. In the case that they post at the same time and their posts contradict each other, one of them could edit their post to fit the other one. Usually it's the second user who has to edit.

Usually, a character sheet is provided when the roleplay topic has been made. But there are some who put their character sheets on the interest checks so that the ones who are interested can go and make their own characters and wait for them to be approved. 

As to what has to be placed on a character sheet. First of all, basic information (Name, age, appearance, [personality is optional], [history is also optional]) and then you go to the more specific ones for the roleplay. As for this one, I think you would need - [Fighting Class, Allegiance (animals guild or some other), Weapons, If wizard, what element?, Spells that they know (I think you should be the one assigning this one), Goal.
