I have a few questions to ask since I'm new here, well one with many parts. Are these against the rules:
1. Having a link to my web site from my game (if posted on yoyogames).
2. Posting on another gaming website (not game making but free game website ).
3. Giving my friend the game I made on cd so he can play it.
4.Mentioning a website in posts
.

1. Not at all, unless the game only consists of a link to your website. Then it's just spam.

2. Certainly not. You can upload your game wherever you want. It's your game.

3. Give your game to whomever you'd like.

4. Most every forum gives their members a signature. It's best to use the signature to advertise websites, as doing that in posts makes them seem like spam.

Thanks
