Welcome aboard! I hope you have success with the tut; if you have any questions feel free to post em up in the tutorial thread (that way folks who come after get the benefit of seeing the question and answer). WIP stands for work-in-progress; the WIP sections of the forum are for posting anything you're currently working on so that others can learn from the process, comment, or make suggestions.
I like your continent shapes! Post up a thread in the WIP section so we can see this come to fruition
