You don't seem to be following your own rules though
But you don't seem to be following your own rules, applying the declared criterion in every case equally ! This is not to offend you in any way ( you do seem to come across as a very prickly bunch though
), but you said somewhere above "We only create subcategories when we have several websites to list in them" -- yet in the category mentioned above [Business_Services > Communications > Translation > Multiple_Language > Asia ] you have a subcategory titled "Brunei Darrussalam" which has ONLY 1 site listed in it !
How is this possible, given your above declaration ? And if Brunei can be created for only 1 site to list, then what's wrong with my suggestion (i.e. creating "Bangladesh") ?
