Temporarily Greatnews doesn't have any help file to teach you to use the full function,So I put together a how-to-use guide for greatnews with step by step screenshot on my website: http://newsgator-herald.blogspot.com/2005/08/blogrssbuzzgreatnews-is-great-news.html
Maybe it can help you unleash the hidden features inside greatnews.
I understand at this stage of beta our developers should concentrate on the construction of software itself, and I also understand that lack of help documentary will make lots of users misunderstand the good of a great software.
So I'm willing to help clarify the wonderful functions within greatnews, and offer my personal little help to all the confused users out there so that jack you can have less worried about this and have more time to develop greatnews itself.
I will update that entry due to any enquiry, and if I can't solved, I will turn to Jack to give the final solution.
By the way, all the screenshots on the website are fabulous.
