Links to personal blogs/homepages are allowed in member profiles and signatures
How much anonymity you want to maintain in your own blog is up to you but it is not against the rules to link to it in your signature.
For myself, I keep my HealingWell identity disconnected from my other online personae. This is not because I don't want to keep my HealingWell friends from knowing I live in Smallville, or that my last name is Kent, but because I don't want some random Googler to be able to find out.
The email address in my profile works. If anyone on this forum emails me and asks I will be glad to reply from my real email address, signing my real name (which isn't Peter by-the-way), and providing a link to my annual Christmas card insert newsletter with holiday wishes, dumb jokes and photos of me, my wife, my kids and grandchildren (the twins who are dangerously cute at 13 months).
You could post an offer to send a copy of your story. That way, spiders, bots and search engines don't have a link to follow. It requires an anonymous email account in your profile. There are several of us here who would be glad to help you set such a thing up.
