Welcome to the Guild! Don't worry about your English, my French is non-existent! Check out the Tutorials section and the Finished Maps, as well as the Monthly Challenge boards - all worth checking out.
Curious though, in the last couple weeks, we've been getting many new members from France... what link did you find our site? I am wondering if there's a link from some major French based site that is leading you all here.
Anyway, do not be afraid post a map you have or are currently working on, the only way to learn is to "do".
