1) Nobody has to pay to install the games or play them, they are completely free.
2) Mochi games force you to watch an advert at the start of the game, this helps them to profit, pay the game developer and most importantly pay YOU for people playing the games. This advert can often be skipped by using the SKIP button that more often than not appears during the advert, however skipping adverts lowers the amount mochi will pay you.
3) If you are asking for the publisher bridge ID, you need to set up a Mochi Publisher account(which you say you have done?) and then go to Settings, and add your Domain to that section. Once it is verified you then scroll down the Settings page to BRIDGE SETTINGS and there will be your Publisher ID.
To set up the Auto Post feature, you will need to go further down the Settings to the Auto Post and then choose CUSTOM BUILT SCRIPT in the selection box, and then in the Auto Post URL you need:
www.YOURSITENAME.com/administrator/compo...p?sid=YOURSECURITYID
Replacing YOURSITENAME with the name of you website, and YOURSECURITYID with the ID Number that you chose in your Admin Backend>Mochigames>Settings section..... for example if you decide your security ID is to be 123.... then you put sid=123 at the end of that above URL.
Once you have done this you should be able to add games from your sites admin backend and not have to go on Mochi again. You can just go to ADMING>MOCHI COMPONENT>ADD MOCHIGAMES and then just start publishing the games that you are wanting with a couple of clicks of a button.
Best of luck with it.
