Wrong instructions for adding yourself to specific mailing list using email
White Rabbit mailing list wiki says this:
> This project's mailing list address is: white-rabbit@ohwr.org
>
> In order to subscribe, please send an empty email to that adress,
with the header: subscribe white-rabbit Firstname Name
However the sympa returns this:
> The following message was sent to list 'white-rabbit' and it seems to
contain
> one or more commands like subscribe, unsubscribe, help, index, get,
...
>
> If your message contained a command, please notice that
> commands should never ever be sent to lists. Commands must be sent
> to sympa@ohwr.org exclusively.
