Yeah, I doubt he stole your work. Sometimes your email get's put into the junk mail pile and they don't see it, so it's a good idea to send it again if they do not reply back in a few days. Another possibility is that they just aren't interested. Most of the time a portal will tell you if they are not interested but they are very busy and don't get to all of them.
Im not sure why flash ninja clan didn't answer, he usually answers VERY fast, like within the minutes.
But once you make one good game that gets popular I think sites will reply if they aren't interested in one of your games because they want to make sure you will come back to them if you have anymore games.
The biggest part of getting a good deal is just sending out your game to as many sites as you can. Not just the main few, because you will be surprised what kind of deals some of the smaller sites give. But it is a good idea to put your game up on a private URL and site lock it just incase a site decides to steal it. Ive never had that happen and doubt that it would happen, but do it if your going to be sending it to sites that sponsor but have no good reputation.
Anyways that was my feelings on everything, take it or leave it :)
