In DOTW, we pretend we are wild horses. Your 'character' is essentially the horse you'd like to be. A 'post' is the actions, thoughts, conversations, etc. we imagine our character to be doing. Yes, it is all written down.
The only images are the ones merely depicting your character.

Once you've registered on the forum itself, you need to join your character. You join on this board, which is the Joining board, and the first board to appear on the main page.
You need to create a new thread and fill out the form which appears at the top of the page, between the head image, and where you're writing your post. This thread should help you if you have any issues with the form.
From there, you wait for an admin to accept your character. The admins are in a box on the left hand side of any page on DOTW.
If you post elsewhere in character before you are accepted, your posts will be deleted. This excludes the OOC board, or this board.

Typically, new members go to the Claiming Creek first, where you create a thread and wait for a reply, or replies. This applies to mares, stallions, and foals.
Other alternatives are to apply directly to a land, or to post in The Free Land.

Honestly, I don't think it matters if you post in third person, second person, or first. You can even post in poetry, though people are less inclined to reply if you do that ;]

Simply no. No characters are allowed to possess any kind of magic or supernatural ability. This means no super strength, super speed, telepathy, vampires, unicorns, pegasi, etc.
You may have your character believe they have one of the above, so long as they do not in reality.

Yes, yes you are.
However, bear in mind that is a zebra mates with a horse, the resulting newborn will be sterile, ie, cannot breed.

Don't ask me this, as the people who become admins are people who I trust, enjoy talking to, and can RP well. If I feel we need a new admin, I will offer the position to the most likely candidate.

These currently go according to the rank of a member. Anyone whose first character hasn't been accepted has a bright green name. Pale orange means that the first character has been accepted. Pink means the player RPs a King or Queen of a land, and purple means they'll make an image for your characters if you ask. Blue means that they moderate one board on the forum, and teal is an overall admin.

In DOTW, we don't require each land to be led by a king. It can either be a King or a Queen - and if there are both, they do not have to be mates.

The most obvious way to get your own land is to challenge the current leader of a land to a battle for the land. This takes place in The Fighting Flat and are subject to the guidelines and rules associated with this board.
Generally, your character finds a home through the Claiming Creek - a member of a herd should invite your character to join that herd.
Finally, you can also post directly in a land and ask for admission to that land. This doesn't happen very often, and is more likely to be a stallion rather than a mare. It's also reasonably unadvised without a prior agreement.
Once you are part of a herd, you may invite others to join the herd, fight for position, etc.

Articblade is a friend of mine. He's nicer than the sometimes appears, especially if he's alerting someone to things they can improve in their writing. He comes from the fanfiction world, not RP, so if anyone cares to attempt to understand, this is method of taking out frustration from terrible writers: [link].
If he's replied to your thread with something sarcastic, or involving imagined violence, you may wish to ask him how to avoid it in the future. If you're very upset about it, come to me and I'll tell him he's been mean.
I am, of course, trusting he won't go too far with this, and that he will be able to help people improve their writing.
