I do mention that there is a forum that I frequent a lot, if asked I say it is a video game or FF fansite, depending on the geekiness level of the querent. I do not keep it a secret, nor do I divide the two. Like Faris said, I have met her "IRL" friends and she has met my roommates, my current boyfriend and my last ex. I also have other online friends too, some of which Phil/HNB knows because we both used to frequent the same site.
