Hello, Dennis! Here's your membership card to the Guild (you'll notice on the back is a coupon for "friggin' sweet mappage"--go ahead and cash that in as often as you like!)
Make sure not to lurk too much, ok? From past experience (both personal and otherwise) people progress a lot faster, feel better about their work, and have much more fun if they post as they learn, asking questions frequently, and becoming an active member. (Plus we'd love your comments on others' maps/ideas, too!)
CC3 is definitely a specialty here, too--and we have some amazing wizards of that software who are so helpful you'll not believe your eyes.
Enjoy, and once again welcome!
