Dear ocamllers, We worked hard on our "Try OCaml" website, started by Çagdas, and we managed to improve it enough, so that we think people can start using it (and hopefully, improving it). It is available here: http://try.ocamlpro.com/ There are 3 lessons, two lessons for "getting a taste of OCaml" (totalling 10 steps), and the last one about some new features in 3.12. You can use the "lessons()" command in the toplevel to get the current list of lessons (in case we contribute more in the meantime !). We welcome any comment to improve it, bug reports, and new content. The repository is on Github: https://github.com/OCamlPro/tryocaml You can easily fork it, compile it, modify it, and send us pull requests if you want your content published on our site. We will probably continue to focus on the first lessons (the "getting a taste of OCaml" virtual section), but we are also looking for contributions on advanced topics : we plan to make them start around lesson 10, and focus on particular issues (modules, functors, labels, objects, classes, polymorphic variants, etc.). Send us a mail if you want to volunteer ! As the engine is translated from OCaml to Javascript by js_of_ocaml, you can even play with it offline, when you are disconnected. Have fun, Fabrice
