I have posted a number of times in the "News/Feedback". There should be a cooking forum. I know CBN has one, and I have been a member there since the beginning. But it is a much less traveled forum. And I am always poking my head in over here on TBN. Having been here since '98 or so, when it was the old Kubota web site, it would have been nice to have the whole time.
Having just put solar on the house, electric and hot water, an alternative energy forum would be nice. Gardening would be too.
In the "News/Feedback" forum, there is a similar thread right now. I am cautious, as a few others noted thee, of the website being overwhelmed with forums though.
Maybe that is why Muhammad and Hakim have kept CBN and HBN going... Possibly they need to advertise those sites better, where some of these forums exist. Would still like to see some of the above mentioned on TBN though.
