Well, you've just found one here, and others on the net.....so keep searching!
If you like that bariatric surgery website so much how come you haven't posted there in 6 months?
I took a look over there and the site is dead. In about a year and a half it has maybe a total of 100 topics.
Edit: I unlocked this thread as it seems you have good intent. Sorry, we get a TON of spammers here who post in a similar manner here.

We are happy to have you aboard.
We do not focus on obesity surgery so much as helping people learn how to lose weight naturally, although we do have some information here along with a good amount of studies relating to obesity surgery.
