I hate doing this but, after running the site open for everyone to Q & A. I decided to make it available for only registered users.
This is mainly due to the spamming that the site content become contaminated and you know contaminatioin is not good for making Natto. :-)
If you have a questions that you don't see in http://nattoking.com/forum/2 (Nattok Making FAQ) and don't want to register, you can simply email the question to info@nattoking.com.
My apology for any inconvinience this may have caused you and thank you for your understanding.
