Very strange site. I got some cult vibes from it, mainly because of the graphics and the vague manner in which it is written. There's a lot of talk about submission and instruction, but not many details on what is expected. It may well be innocuous, but it strikes me as creepy.
I agree, there is something very strange, sort of cult-like and/or/including New Age about the site
And its defintely not a Biblically based site, which they state in the small print of their home page;
"the instruction described in this site is by no means church-related. It is not for those who wish for Biblically based guidance nor for those who are offended by overt sexuality and intrusive discipline."
