A few basic GW questions

I've got a few questions about Guild Wars which I'm sure a most of you can answer

1. I noticed that in the list of contents for the GW speicial edition it said it had software that let's you talk to people on the game. Can you still do that if you have a microphone or do you have to get the thing that comes with the special collectors edition?

2. Are the controls easy? What are the basic controls?

3. Are guilds created by members or by the people that made the game?

4. What are some of the skills you can level up?

1. You dont need the CE to get teamspeak. You can set it up or use other methods yourself.

2. Point and click and keyboard controls.

3. You can create the guild yourself. Cost gold though so save up.

4. Use the search button to find about skills.
