No Longtext

I'm using the events sample as a template and trying to duplicate the evcategories and evevnts tables as newscategories and newsevents.

1. I don't see a way to copy a table to another table.
   
2. when I try to manually reconstruct the table evevents, I find that the longtext field type is not offered to me as an option.
   Can you help?
