We don't need to be expressly invited. Membership is not by invitation.
I can agree with that, in the sense that a forum really can't be fully defined with a line of text. We have a pretty diverse crowd here, and if it grows it will only get more diverse. Of course you want to say something that references card reading/divination, and you want it to show up in a search, but you want to be intriguing, too. Be just a bit vague and arouse curiousity, it's more enticing that way.Also, an emphasis on "practical" seems to exclude the more theoretical approaches that for instance Golden Dawn aficionados are so fond of.
