Welcome to the Guild Rene, I'll be glad to see what you do as you get to be good friends with your tablet. I got a cheap one awhile back and I'm really enjoying it. And I probably use it for a tiny fraction of what I should do with it. There are a lot of amazing tutorials here, and lots of people with their hands on tablets, so you'll get great guidance. Jumping right in and posting a map is absolutely the way to go.
I just want to mention though, you sound like a really nice, humble, and respectful person so I'll ask that you not be too quiet here in the forums
Just because you're new here doesn't mean your insights on other people's maps won't be welcome. Share your maps, share your experience, and enjoy your stay here! I look forward to you pointing out some grievous errors on my maps soon
cheers,
Meshon
