I believe their site is a Ning site, so if you want to leave that site go to "Settings" either on your profile page, of just look under where it shows your name, inbox etc on any page you are on. Once you've clicked on "Settings", select "Profile". This gives you the option of changing your profile page. At the bottom of the edit options, you should find it says "Leave..." with the name of the website. Click on that and it should give you an option to delete your profile page and any content you've added (assuming you want to remove all of your content before you leave). If you don't have the option to delete your content, but you want to remove it, then you may have to back out of that and manually delete your content before going back to "Settings" and deleting your profile.
Alternatively, you can email their site admin (there's usually a "contact us" or "report an issue" button on most Ning websites) and ask them to remove your content and profile page, explaining why you are leaving. If it is actually Josh's site though, I strongly doubt that he will do that, so you may want to try and do it yourself if possible.
Please feel free to ask me if you have any more questions, I'll do all that I can to help you
I picked interest on you after going through your short profile and demand it necessary to write you immediately. I have something very vital to disclose to you, but I found it difficult to express myself here, since it's a public site.Could you please get back to me on(email@example.com) for the full details.
