Never used DW in my life... but I can have a guess for you.
If the ARticle is held in a DB, then you should beable to "fetch it"...
If you have cvreated the article so it has split content fields "a blurb/intro field" and "a main body field", then you can simply put a call into the blurb field.
Alternatively, you may have to call in the article and then set a limit on the number of characters returned etc.
Alternatively, yes, you could type it by hand (the only option I know of if the site is not DB based?).
