hi,  
i am not sure if i understand white\_list plugin. i am building an app  
where users can post messages. i would like to use white\_list to remove  
html markup and any javascripts. however when i do the

WhiteListHelper.tags.delete = %w(img strong em b) at the end of my  
environment.rb those tags are still available in the post view. how do i  
configure so users can not use the img, strong, em tags, etc…

thanks for any bones tossed my way!
