Thanks so much for this note, Linda. First of all, about losing your post. Go into your revisions. Under the three dots you’ll find a link to your history revisions and you should find your draft with your text.
Also, it’s not so much the length of stories I don’t think, but whether people read to the end. In looking at my stats today, I have long stories get short member reads and vice versa. So I think the key is to write compelling reads that will keep people interested to the end. I hope that helps.
