If you are interested in learning or teaching Ocaml, or just curious, you can use the ML ocaml_beginners@yahoogroups.com.
You can browse the archives of the ML ocaml_beginners at http://groups.yahoo.com/group/ocaml_beginners/
The description of the ML is:
"This list is a place for the mutual aid of those who recognize that they’re not ocaml gurus yet... everything you wanted to ask about Ocaml, but were afraid to ask in the very official caml-list@inria.fr, can be asked, answered and discussed here.
Satisfaction is NOT guaranteed and if you are teaching more than you’re learning... please think that you’ve probably learnt more than you’re teaching! :-) "
