I've had a quick skim through some of the past BB stories and didn't find a mean or negative comment on any of them. Maybe the Pros fandom is better-mannered than some other fandoms, or more appreciative of the effort that writers put into their stories and the courage and generosity with which they then share them. Either way, I hope you're reassured a little by this. If you're still horribly worried, and have not already done so, why not post a few Pros short stories or drabbles online and see how they are received? That's what I did with my Pros artwork and I'm so pleased that I did, because everyone was really kind and I had some lovely feedback. :-)
