A coven is not going to publically display the address of where they meet and allow any old person to turn up, that would be ludicrous.
They want to avoid untrustworthy people, and people who are a little crazy, and as such will most likely want to converse with you over email and interview you before alowing you to be a part of their proceedings or telling you where they are.
They have an email address at which you contact them, I suggest you do that.

Looks like you may have found a good group. At least the High Priestess is properly trained and has the experience to help those newer. You can contact them through the link on the witchvox page that says "To send a private email message to Nautilus Coven ..." It is very likely that you may exchange several e-mails before an introductory meeting is set up to see if you'll be a good fit for the coven.
Remember that covens are very close knit groups and not everyone is suited for a particular coven. Just because you want to join Nautilus Coven doesn't mean that you will be accepted. But just be yourself and be open and honest about what you are seeking and see how things work out.
