I have a few problems with my DB.

1 - After importing the data from Dmoz.org into MySQL (I am trying to build a website via powerseek using Dmoz DB), I have a number of variables with the same name: how do I merge them?

2 - Many of the static html pages that should be auto-generated result "hidden", even though the respective database field was left unchecked: how do I fix that?

3 - Many of the languages (Arabic, Chinese...) do not appear: instead I have a series of "??? ???": how do I fix this?

Thank you
