I came across this site http://www.diffen.com/difference/Buddhism_vs_Sikhism which allows anyone to edit the comparison table.!!! I have since corrected information in some of the rows . Limit is 250 chars. As anyone can edit the table the info does change. History does not seem to show all the changes!
I am going to work on a similar comparison table and will be publishing it here. Help will be appreciated for any addition or corrections.
