Hi Johnt, got your mail. thanks :)

Rawsugar? Like most Rawsugar exports to XML.
 To my knowledge, none can directly import like they do for del.icio.us or Furl.
So you'll have to check out those that can import, or extract, from XML/RSS. Yahoo can.  You can also try those that import and export their own XML format, like Blogmarks, it may work.
I've tried importing not specified formats to Linkagogo (to convert), I can't remember what but some did work.  (Linkagogo has many converters.)
Also some import del.icio.us RSS, maybe it's compatible with Rawsugar?
