Use CASE:

SELECT regname, 
       regemail, 
       regphone, 
       regorg, 
       regcountry, 
       datereg, 
       CASE 
         WHEN website IS NULL THEN 'no website' 
         ELSE website 
       END AS WebSite 
FROM   regtakepart 
WHERE  reject IS NULL 

or COALESCE:

....
COALESCE(website, 'no website') AS WebSite 
....
