Base Mailing List
Alternatively (and better), subscribe to the list by sending a mail to firstname.lastname@example.org.
You can post to the list without being subscribed to it. However, note that in this case your mails have to pass moderation, which might delay them.
A mailing list scales much better than private mails to single persons: More people can read your mails and possibly answer it, and more people can learn from your answer. This is what "community" is about :)
So, usually it is a good idea to try the mailing list before sending private mail to any of the involved people (though there are exceptions, as to any rule).
There's also a developer's mailing list in the Base project, called email@example.com, everything said above also applies to this list. Subscription is via sending a mail to firstname.lastname@example.org, alternatively a news gateway exists at Gmane.
