How can you not know what skype is? everyone uses it nowadays.
You don't have to give your name if you don't want to. Personally, I used "Christofer.laurell" because I lack imagination and needed a username.
Some skype members has aliases like you got now. You could register an account as "Stryderzero" if it makes you feel better.
Also, let's have a chat before you work. To ensure that we are both satisfied with the result.
Here's a picture of what a typical chat generally looks like.

It is possible to chat using your keyboard or using a microphone and if you want a webcam, as well.
It also has the nifty feature of allowing me to share my computer screen, as I work on it, with you. Allowing me to show you stuff.
You can do the same. For example, while you make the terrain I can occasionally glance at your progress,
throw out ideas and suggestions if you want them, or simply allow me to get a better view of the map without me downloading it. ;P
It also enables me to quickly send you stuff which prevents further abuse of pastebin. Important stuff tends to be pastebined just to enable you to redownload it if something happens.
