Advertising, Where and What?

I've been hunting around the forums lately and have noticed a lot of Howrse players asking where they can/can't advertise. So because of the lack of knowledge regarding Advertising we thought we'd fill you in.

 

What is Advertising?: 
Advertising is where you tell people about a service you're offering or something you're looking for or believe in. 

What can I advertise on Howrse?
It varies depending on where you plan on doing it. Here is a list of places and what is acceptable there.

- Your Presentation: On your page you can advertise trades, services - both for your personal breeding farm (sales, coverings etc) and your EC (Jobs, boarding etc), you can advertise a giveaway or service of another player. You may also advertise your religion however this is limited to a small wordless image. You can also advertise your ideas that are in voting.
  Hint: If you want more people to check out your page, go give some congratulations. 
- Your EC Presentation: You can advertise the same things here that you can advertise on your personal page however most people just use it for their EC.
-  Your EC Forum (International) You can advertise the same things here that you can on your page. You can also allow others to advertise. 
- The EC Forum - Specifically designed for offering board, offering jobs etc. This is the only thing that can be advertised here. 

What can't I advertise on Howrse?
You can't advertise religion (other than stated above) nor can you advertise politics. 

Where can't I advertise?
 Read the places below.
- Personal Messages: So no spam, no advertising. You can't even advertise via your email if it is for your EC.
- Forums (Other than EC forum) You can't advertise in the Game play forum or the Events forum. You will lose karma. 
   Hint: You can't even ask where you can advertise (in the forums) as this is also seen as advertising.
- EC forums of others, The exception to this is if you have permission.
