[Crow102]

Hi like I said im really new to the emulator scene and did not even know people emulated online games but anyway on to my questions.

1.Like I said earlier im really new to this whole emualtor thing and was wondering is it easy to setup and play?
2.Any Fee's at all?
3.Is there a certain server I should look for?

thats really it and as I said im a complete newbie to all this and this will be my 1st online game emulator so if anyone could help me out it would be great.
