AIDA's mailing lists
There are three main mailing lists that AIDA makes use of:
The 'liste_AIDA', which is mainly used for official information, it's not really used for debate.
http://sports.groups.yahoo.com/group/liste_AIDA/
The 'chat_AIDA' list, this is used for most of the open debate, here the word is free (within ethics, obviously).

Finally, there's also the 'athletes_AIDA' which is debate between competing freedivers. The discussions here have as much influence on AIDA's decisions as IOC's athletic commision have on IOC's work. This list has become quite important this last year.

This list is closed, though, but if you have competed in an AIDA competition within the last year you're elligable for it. Send a mail to Sebastien Nagel
aida.international@bluewin.ch and ask about the procedure (it's one mail).
Other than that, AIDA have closed lists for the official work of the Assembly and for the Management Board, and I think a few others.
And don't worry, English is main language on all these lists.
Hope this helps,
