I would think it was closed it due to link violations...as I recall there were a couple of direct links to other hobby related forums which is a violation of this sites policy and user agreement.You have put together a couple of well researched articles for the membership here and efforts in that regard are appreciated...but in the future it may be a good idea to refrain from posting direct links to or even reference to other hobby related sites.
If you want to discuss this with me directly feel free to contact me at:
