If you referred her to this website, she could very well be reading your post. I wouldn't worry about referring her here - there is helpful info for everyone, and I wouldn't worry about the 99 vs. 99.9. Still, since your identity is not masked, you might want to reconsider talking about someone who might recognize herself. I don't think it will be awkward if her son isn't at the same level as yours - they're friends, right? And regardless of his exact LOG, I'm sure you'll have so much helpful info to share.
