I have a different screen name I use on other (non-poly-related) forums, a blog, and groups. For this I wanted something new, unique, and that wouldn't come up associated with those things for privacy reasons.
I've always identified with the lyrics of the Sarah McLachlan song, "Elsewhere." It seemed fitting to use "myelsewhere" as a screen name. I feel like it's a tribute to finding my happy place in the poly world -- not everyone will understand, but it makes me feel more fulfilled.
"I believe this is heaven to no one else but me.
And Iíll defend it as long as I can be
Left here to linger in silence
If I choose to, would you try to understand?"
"There came a time when the risk to remain tight in the bud was more painful than the risk it took to blossom." ~AnaÔs Nin
