I think they decided to close the forum for their own reasons.
The pity is I only started posting on forums to give people information and ideas to help them. When I started building my Nisota I could not find enough information without having to pay for some, which I thought, I did not want to do.
I know conversions are not everyone's cup of tea, but if you can get the right advice it can make it easier to do.
So the loss of a forum which had a lot of information on, is a loss to anyone who wanted to have ago themselves.
