Posting an entire story on a weblog can be a problem, especially if the story is longer than a page or two. The narrow column format of most blogs doesn't suit stories, and visitors may find all that text off-putting.
One way to solve this problem is to upload your story to your personal FTP space and posting a link to the story URL on your blog. That gives your visitors the options to read or not to read.
Here's one of my stories, Roomies, which I uploaded from a file copy that I saved as a web page rather than a word document in Microsoft Word. I didn't fiddle with the formatting or coding; this is exactly how Word converted it. You can also convert a story into .pdf format and upload it that way -as I did with my story Red Branch here - just be sure to designate the link as a .pdf file so that your readers know what they're opening (some folks on dial-up have to download .pdf files versus opening them online.)
Once you have a story saved away from your blog, you can post a permanent link to it on your sidebar. A story posted as a blog entry will drop down as you post new entries and eventually disappears into your archives; a sidebar link stays visible for as long as you keep the link there.
